The files I posted before had a typo. My attempted fix (sans typos) is now in 
the
trunk version (http://code.google.com/p/wordpress-geo-mashup/source/browse/). 
Since I
don't see the problem in my version of PHP, I can't be sure it works. Please 
let me know.

Nope, with the trunk version of geo-mashup.php and render-map.php render the 
admin
side completely unusable with a double header send error and the main site 
displays
your notes on the trunk php version.

I dropped the notes out of the bottom of the geo-mashup.php and got the admin 
section
to render, but I still get the same error.

Error when logging into Admin side and clicking on the geo-mashup plugin 
settings:

Fatal error: Cannot use string offset as an array in
/home/findwire/domains/findwirelessinternet.info/public_html/wp-content/plugins/
geo-mashup/geo-mashup.php
on line 615

Error on the mashup page map.

Fatal error: Cannot use string offset as an array in
/home/findwire/domains/findwirelessinternet.info/public_html/wp-content/plugins/
geo-mashup/render-map.php
on line 96

Thanks so much for looking at this !  

I tried the current trunk and the diff trunk from 8/3 without any difference,
currently I have the original beta3 files on the server.

Glenn

Versions from my server:
Apache 2.2.8    Running
DirectAdmin 1.32.2  Running
Exim 4.67   Running
MySQL 5.0.51a   Running
Named 9.3.3rc2  Running
ProFTPd 1.3.1   Running
sshd    Running
dovecot 1.0.10  Running

Ok, I think my fix may have worked, but the error popped up in another place. 
The
trunk now contains a second round of fix attempts if you'd like to try it. Same 
two
files.

You supplied versions of everything but PHP - that's the one I'm curious about. 
I'm
on 5.2.6.

Got the same error with the version from doanloads. Even with the versions from 
the 
trunk, it is not displaying anymore.

Any hints?

Can you give me a URL to look at, or at least a full copy of the error message?

Thanks Dylan,

  PHP ver 5 is what my host reports, but they don't report the version in Direct 
Admin nor in the Forums.  

www.findwirelessinternet.info/mashup

mashup/render-map.php on line 96

I'm not finding any other solutions suggested for this other than upgrading 
PHP. 

You might be able to figure our your PHP version by creating a file on the 
server
with just this in it:

<?php phpinfo(); ?>

and hitting that with a web browser. At this point I'm not sure that will help 
me
much, though.

I'm getting a similar error.  Dylan, if it would help, feel free to peek at 
http://www.theglobalguy.com/info.php.

Fatal error: Cannot use string offset as an array in /home/henrym/htdocs/wp-
content/plugins/geo-mashup/geo-mashup.php on line 613

Thanks, that does add some information. You and I are running the same version 
of
PHP, 5.2.6, so there must be some difference in the configuration that causes 
the
error. Here is your configuration:

'./configure' '--with-layout=GNU' 
'--with-config-file-path=/usr/local/etc/RCW/php5'
'--with-config-file-scan-dir=/usr/local/etc/RCW/php5/config' '--disable-all'
'--enable-libxml' '--with-libxml-dir=/usr/local' '--enable-reflection'
'--program-prefix=' '--enable-fastcgi' '--with-regex=php' '--with-zend-vm=CALL'
'--disable-ipv6' '--prefix=/usr/local' '--mandir=/usr/local/man'
'--infodir=/usr/local/info/' '--build=i386-portbld-freebsd6.3'

and here is mine:

     './configure' '--enable-discard-path' '--with-gettext' '--enable-exif'
'--enable-bcmath' '--enable-calendar' '--enable-magic-quotes' '--with-curl'
'--enable-ftp' '--with-gd' '--with-zlib' '--with-t1lib=/usr/local'
'--with-jpeg-dir=/usr' '--with-png-dir=/usr' '--with-zlib-dir=/usr' '--with-ttf'
'--with-freetype-dir=/usr' '--with-imap=/usr/local' '--with-imap-ssl'
'--with-mhash=/usr/local' '--with-mcrypt=/usr/local' 
'--with-openssl=/usr/local/ssl'
'--with-mysql=/usr/local/mysql5' '--with-ldap' '--enable-mbstring'
'--enable-inline-optimization' '--with-iconv' '--enable-pcntl' '--with-pspell'
'--with-bz2' '--enable-sockets' '--prefix=/usr/local/php5' '--with-xsl'
'--with-config-file-path=.:/etc' '--enable-soap' '--with-mysqli'
'--with-pdo-mysql=/usr/local/mysql5' 

I'm not sure at this point which option or absence of option to suspect. If 
anyone
else getting the error can post their configuration info, it might help narrow 
it down.

Hey Dylan,

I've been doing a bit of research on this, but unfortunately I'm a network guy, 
and 
not a coder.  I've found a few hints on differences between PHP 4 and PHP 5, 
including some stricter coding standards that are now being enforced.  One in 
particular is the third line on this site:

http://www.php.net/manual/en/migration5.incompatible.php

Illegal use of string offsets causes E_ERROR instead of E_WARNING. An example 
illegal use is: $str = 'abc'; unset($str[0]);. 

Does that make any sense? 

See if this helps as well:

http://www.zend.com/forums/index.php?
t=msg&goto=6396&S=05a0af54d2545c67e9f72ffc5ae34c74#msg_6396

Ok, I've got a fix.  From my limited understanding of the error, it's caused 
when a 
string is treated as an array.  Simply adding the line

$geoMashupOpts=array();

Above line 613 seems to have fixed the problem for me.  I think I'm using a 
sledgehammer to fix the problem, but it's good enough for the moment.

I used the information on this site:

http://informationideas.com/news/2006/06/14/fatal-error-cannot-use-string-offset
-as-
an-array-in/

to hack in my fix.

Thoughts?

Well, that fixed the initial problem, but now the plugin doesn't seem to be 
able to 
read options stored in the database.  When I got to the options page, it's 
always 
blank, but if I look in the database itself, the options are updated.  Even 
though 
I've got a valid key stored in the database, I'm getting the google key error.

Sorry for the multiple messages...

I fixed the previous error...I just moved the $geoMashupOpts=array(); line to 
the 
top of the file.  It now looks like this:

load_plugin_textdomain('GeoMashup', 'wp-content/plugins/geo-mashup/languages');
$geoMashupOpts=array();
$geoMashupOpts = get_settings('geo_mashup_options');

I have this error and I'm running PHP 4.4.8 @ dreamhost. 

The offending code is on line 614, somewhere in here:
$geoMashupOpts['category_line_zoom'][$category->slug]

It's trying to refer to a string position 
($geoMashupOpts['category_line_zoom']) with
 an array reference (apparently). I tried declaring
$geoMashupOpts['category_line_zoom'] as an array, but that didn't help. I also 
tried
declaring the $geoMashupOpts as an array as henrymalmgren suggests, but it also
didn't help.

Any other ideas anyone?

mrgreenfur, can you try this version and let us know if it works? It's 
combination of
henrymalmgren's solution and some array testing in your problem area.

[deleted comment]

Dylan, the settings page now loads okay, but the default values for some 
options are
strange and the page doesn't seem to update properly. The value for all of the
options is set to "U" and doesn't update when I drop in my maps api key or 
default
zoom level, etc.

Not sure why...

That's not good - the long unsolved Issue 87:
http://code.google.com/p/wordpress-geo-mashup/issues/detail?id=87. There is a
workaround there, although it's somewhat painful. Sorry, I wish I had a clue 
how that
happens!

At least issue 87 is easily resolved. I erased a few rows in the DB and it 
seems to
work. For some reason under 'overall settings' I can't change the 'map control' 
to
anything other than 'small zoom', it always reverts back. 

Anyhow, your fix fixed it! Thanks for the help!

mrgreenfur, would you be willing to try this file? I had some ideas for 
preventing
the Issue 87 problem. Thanks!

Well, I went ahead and put it in a new release. I hope it works for everyone.

Hey Dylan,

I just tried the new release, and it seems to have solved the issue for me.  
Thanks!

Henry

I am echoing Henry's sentiment!  You are awesome. . . The newest release solves 
my
issue completely and my maps are back online with WP 2.63 and the latest 
Geo-Mashup
version!

Thank you very much.
Glenn

Thanks for reporting back! We'll call it verified and hope that's last of it.
