What does your error log say?

Have you checked "line 315" of /var/www/store/passionsoap.php? There might be something wrong w/your script.

RE: "PHP Fatal error: Allowed memory size of 134217728 bytes exhausted...", you need to bump up the memory limit in your php.ini file.

this is on line 315:
$spotlights[$i] = $this->_hash_product($spotlights[$i]);

I got 128 M in php.ini

I don't think I get the store to work,awell thank you for your effort :)

"I got 128 M in php.ini"

Try bumping it up to 256 M

Did bump it up.Did'n't change a thing.Guess it is just a script thing.I got no problems with wordpress.
Thanks :)

You shouldn't set it to 256M - that's the limit of *each* process not the all the processes. Setting it to 48M is enough for almost all of the heavy applications. ~20M is enough for Wordpress.

I believe it's trying to access $spotlights[154120] which is obviously not correct. You probably have a broken loop in your script.

Thanks for answering Kamal.
I deleted that buggy script.Even tried it on another host, didn't run either :)
