HI @freeworld,

Please navigate to the Dashboard > Forums >  Settings > Styles admin page put the following CSS code in the "Custom CSS code" textarea:

#wpforo #wpforo-wrap .wpforo-recent-wrap .wpforo-recent-content td.wpf-spost-title .wpf-spost-title-link {
font-size: 17px !important;
}

#wpforo #wpforo-wrap .wpforo-recent-wrap .wpforo-recent-content td.wpf-stext {
font-size: 14px !important;
}

The red marked value can be changed.

Don't forget to delete all caches and press CTRL+F5(twice) on the frontend before checking.

thank you for your reply

I try this code but it change all new posts but I need to change old posts as well

for example one of my forum has old 232 posts and most of them are different when you see.

I can edit them one by one as a moderator but it take a loooot of time. I am looking for other way.
