Apache error messages displayed when loading Studio. The Web server path is set by using the IP address. Apache: [Thu Feb 26 14:49:18 2004] [error] [client 192.168.4.13] open: No such file or directory [Thu Feb 26 14:49:18 2004] [error] [client 192.168.4.13] open: No such file or directory [Thu Feb 26 14:49:18 2004] [error] [client 192.168.4.13] gd-png: fatal libpng error: Invalid number of colors in palette, referer: http://192.168.4.13/testsuite/studio/ [Thu Feb 26 14:49:18 2004] [error] [client 192.168.4.13] gd-png error: setjmp returns error condition, referer: http://192.168.4.13/testsuite/studio/ PHP: No error.

Is it possible that the server would have multiple conflicting versions on libpng on it? i.e. the usual deal with GDAL's builtin PNG, GD's use of system libpng, and PHP-GD coming with its own builtin GD.
It appears there were two versions of libpng. This problem does not appear anymore. This bugs is marked as closed.
Reappering now when after opening Symbolizer. Steps to reproduce: 1. Open a context file. 2. Open Classifier. 3. Select "Polygon" feature type. 4. Open Symbolizer. 5. Message appearing again in log file.
Could be a conflict with GDAL's built-in libpng. You may have to recompile GDAL and force it to use the system libpng (and jpeg at the same time).. i.e. using --with-png=/usr --with-libz=/usr --with-jpeg=/usr (Change /usr above with the path to the 'prefix' where the corresponding system lib is installed.) Then rebuild php_mapscript
