SMF For Free Support Forum

I removed the poll from that topic. At the very bottom of the thread there is a link called remove poll click that it and it will remove the poll.
I did review your permissions didn't see any issues.

I did do a couple minor fixes on your site for the forum to be secure for certain images and in the css.

Also if you are members are missing pictures from old sites check out archive.org wayback machine you might be able to recover them. Either enter the thread url or the direct image url.

Send me the link to that topic if you can.

It just checks for errors with attachnents
Example
The follow errors were found during maintenance. Check the box next to the errors you wish to fix and hit continue.
15 attachments/avatars have an entry but no longer exist on disk
1 avatars no longer have a member associated with them

Done

Gallery-  Admin -> Configuration -> Gallery configuration -> bottom of settings page If you wish to uninstall this mod click UnInstall now
Calendar -> Admin -> Calendar -> Enable Calendar


I think you can hide the rest with permissions for guests and normal members
