Re: Version mismatch: lesson can't downgrade 2005110200 -> 2005060900 ! Virgil Ashruf - 2011年09月20日 星期二 18:58 回帖数:0 I've just ran into this error. I solved it to edit the version field of the module that was giving me the error in the table mdl_modules. It might not be clean, but it saved me from having to delete the complete database of this site. 平均分: - 永久链接 显示父帖 回复
