   Everything had been working fine for over 6 months, then suddenly yesterday I started to get the following error all over the admin side of the blog

   Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 72865 bytes) in /home/*username*/public_html/blog/wp-includes/cache.php on line 48

   On the dashboard page, all the content streamed from WP has disappeared, all my scheduled posts have disappeared too.

   If I click on manage - I cannot see the posts list - it is replaced with the error above, and when editing any unpublished page, everytime I click save or save & continue editing, that error appears as well and I have to hard edit the browser URL back to admin home and go back in through manage -- pages -- select page and edit.

   The cache.php is the standard file as supplied with the original download, and line 48 seems to refer to the strings for the $server, $host, $database, $user, $password, datas.

   The public side of the site is working, and I can write and publish new posts and pages, but the admin back end is a mess, and I've lost all the scheduled posts - days of work :(

   Can anyone suggest a fix on this?

   Thanks

   I searched the forum and found many posts on this problem, all boiling down to this answer.

   Now, I noticed you are still on version 2.3. You should definitely upgrade. But back everything up first! Here are directions on how to do back up.

   Thanks Rosie .... but eek!

   Regarding the fix - my reply on the thread you pointed to says it all.

   Regarding the back up - it looks like a terrifying task, especially when it starts waffling about anti-spam etc swelling the database and needing to not be backed up.

   It's 5am here and maybe I'm too tired - I'll look again in the morning after some sleep

   Thanks again

   Heh! My bad. I should've seen you'd already been to that particular post.

   Here is Codex article with a few more details. As it says, your host may not allow you to change the PHP memory size; that you have to ask them to do it. It should be no biggie to do.

   And regarding the backup, it's not so difficult... even a goober like me can do it, and I mess everything up!

   Print out the instructions, and ignore the part about your spam plugin swelling tables--just select all the tables and mark the boxes as described.

   I can't tell you how important backing up your database is. It has saved my prodigious derrière more times than I can count.
