3.0 worked fine but now I cannot log in at all

Hi all,

I upgraded to 3.0 and had no problems. I am using Atahualpa as a theme. Everything worked fine for a month or so and now even though you can see the site, I cannot login into the Dashboard.

I keep getting this error: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7680 bytes) in /home/marisaco/public_html/news/wp-admin/includes/template.php on line 3509

I don’t understand why it needs more memory, when it was running on 3.0 and was perfectly fine before for about a month? There were no changes made to the site during that time.

Someone mentioned changing php.ini . I don’t have such a file and I cannot install one under the PHP configuration option in CPanel. I have contacted my host but is there anything I can do or is there different cause for the problem? Unlike other threads with the error, it does not seem related to a plugin.

Thanks, Marisa
