Thanks for the reply. you will have to forgive me, as I am VERY unfamiliar with all this stuff. Where would I go to change the MySQL .ini files like you indicated in the other post? I am using a hosting service for my site, wouldn't this mean they would have to change the version of MySQL on their servers? Wouldn't this affect every one else that has a database on the same machine as me? Or would it just affect my database? Also, if I choose method three from your post; "Execute the query SET GLOBAL sql_mode='MYSQL40'", Would this affect the rest of my message board's features? I am running vBulletin3, with v3 Arcade and some other plug-ins.
As for the direction of the 'slashes', I did not enter that directory path anywhere, it had already been filled in for me on the 'Step1' installation page, correctly I think. But when the error message came up in 'Step4', the last slash was printed opposite from the others and the beginning of the path was spelled wrong. Is it picking up an incorrect path name from somewhere? and how would I fix it if it was?
