XF 1.5 Error on import new addon

[1goodname]

Hi, i'm geting this error (Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 12 bytes) in /home/cshp/web/cshpforum.com/public_html/library/Zend/Db/Statement/Mysqli.php on line 276) when i try to import a new addon (I already tested 4 differents addons and all give me the same error), i already tryied to change memory limit to 256, 512mb and -1.
Any fix? (My vps have 4gb ram)

Your memory limit appears to be 32MB. This is potentially specified somewhere such that it can't be overridden by XF. It may even be overriding your php.ini value. If you try to increase the memory limit and you keep getting that specific allowed size, it's being overwritten/prevented from somewhere else.
