Thread:Project:Support desk/Errors when using GD image library/reply

If you have both 1.24, the problem may be one setting in LocalSettings.php causing an error, or if you forgot to run the upgrade script on the migrated database.

It's strange that the debug log stops at that line. That may indicate a fatal PHP error or, in the worst case, a segfault. Note that PHP fatal errors aren't logged in the debug log, you should enable the display of PHP errors (see Manual:How_to_debug) or look at the error log of the webserver.
