I did delete the mysql database!
I deleted the Mysql database.
I Created a new one on the host server.
Uploaded the new version of php 2.0.22 to the new mysql database.
Restored the forum backup to my new version php 2.0.22 using the Restore Database in the general admin.
I have got rid of the error & my forum is upto date but with no content.
The forum backup has restored 350 posts, 102 topics, which all show on the home page. But all that content has gone!
Also i am now the only member previous members have vanished.
Have i deleted all the content by deleting the mysql database? Or can i retreive it from the forum backup i made & how?
