Hi. I've searched this error message and have seen similar problems, but none of the solutions work for me. Mine is a little different. My site, blocks.pro, loads fine(painfully slow, but fine). No errors I can see. I can't access the admin though. I get this error message:
"Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 122880 bytes) in /hom........l/wp...../pluggable.php on line 1163"
I've already adjusted php.ini up to 96m a few months ago, today I raised it to 128m and still got the error, but after that my main site wouldn't load. I put it back to 96m and renamed my plugin directory and then I could get access to wp-admin. For some reason when I re-activate my plugins the error comes back, but I can't get all the plugins back, only some. Yesterday everything was fine. I did add the wp-no category base plugin yesterday, but it still worked after that and deleting it didn't help. Any ideas? Thanks. Newest version of wordpress, btw and buddypress as well, but again, no trouble at all yesterday.
