I have to edit a section, it asks me this:
be any way to resolve?
One table is missing in ur sql database
it cannot be a bug - might be corrupt file(s) in admin directory / corrupt database tables
needs to be analyzed by an expert ..
Any weird plugins? MY_TABLE_PREFIX does not occur anywhere in MyBB's sourcecode.
What plugins you've installed ?
Do you have My Plaza or something?? Some of Pirata Nervo's plugins use this.
