Cannot log into WordPress Admin Dashboard, getting fatal error

Hello everyone,

I hope someone can help me, I am going crazy and wasting lot’s of time on this problem. I cannot log into my wordpress admin dashboard. I get this error:

Fatal error: Allowed memory size of 262144 bytes exhausted (tried to allocate 49152 bytes) in /home/freedi5/public_html/wp-login.php on line 194

I have seen all the post about increasing the PHP memory limit and have done that, hopefully correctly. I just went through a post that listed many things to try if you cannot log into wordpress and still I get the error. This is driving me crazy, I have reinstalled a new copy of wordpress on the root, but nothing seems to work.

Hopefully someone can help.

Thanks for any help you can give me,
Bob
