Problems with apache zlib.output_compression turned On

[NilsLindenberg]

Reported by gpuk2 on #wikka:

[23:19:08] <gpuk2> I have just installed Wikka v1.1.6.4 on to our webserver (Apache 2.2.8 with PHP5.2.5 and MySQL 5.0.45) - the installation wizard worked flawlessly and successfully created the database tables and php config file

[23:20:14] <gpuk2> However, on first view of the defualt homepage all we get is garbled characters - it's totaly garbage e.g. ??b?0x11h.C?n0x12?}? P?!0x12??B!N L|and so on

[00:02:32] <gpuk2> fixed! the problem was double gzip encoding i think

[00:02:42] <gpuk2> we use apache's mod_deflate to do all the compression

[00:03:12] <gpuk2> but i just discovered we had zlib.output_compression turned On in php.ini

[00:05:41] <gpuk2> no idea of the implications, nbut perhaps you could consider adding "ini_set("zlib.output_compression","Off");" to the top of wikka.php (just before the call to ob_start() )? Apologies if this is a dumb idea

This appears to be a system configuration issue. I've added this to the [ WikkaTroubleshooting] page in case others run into the same issue.

There really is no conceivable way for WikkaWiki to keep track of every possible permutation of Apache modules in use that may affect Wikka.
