Re: Modify Php Settings With .htaccess File
-----------------------------------
[quote user="Mighty Gorgon" post="19070"][b]buldo[/b], you don't need to set it via HTACCESS, because you can set it via PHP on your server...

Why you want to raise Memory Limit? Are you having white pages or some other warning? [/quote]

I've got a "Memory execed limit"  with "Rebuild search index" in ACP->DB Maintenance, using the standard IP parameters. 
I must reduce "Max post size" in  ACP->DB Maintenance->Configuration to 250 to complete the task.

I've also tried to insert "ini_set('memory_limit','32M');" in config.php as suggested on other post, but the error remains.

Ciao,
