I'm randomly getting the error:
PHP Code:
Fatal error: Out of memory (allocated 4980736) (tried to allocate 491520 bytes) in /home/noteable/public_html/zencart/includes/modules/meta_tags.php on line 265 
when browsing a store I'm working on (admin side as well)

I have not made any changes to the meta_tags.php file but the error is always on the same line 265. However when I get the error If I just wait a few seconds and refresh it usually goes away.

I'm curious if anyone else has seen this error and knows more about, or perhaps if there is a problem with the host's server.

you may be able to see the problem by browsing here:

Thanks!
