tested pagination , created few topics , clicked paging everything works http://prntscr.com/jpofdb

Only thing to try is move the order of YJSG plugin. I cant replicate the issue.

[Rollmodl]

Ok, thanks.

Just tested messages per page , everything works on my end. YJSG overrides Jpagination to add class names ,

this

Fatal Error: Cannot declare class JPagination, because the name is already in use in

tells me that YJSG was to late to do so since something did it before, thus moving plugin order might help. Just try to set YJSG first or last
