Tetra-WebBBS Support Forum
Unfortunately a security leakage was detected and brought to my attention last night.
Tetra WebBBS 6.11 is a quick fix to the issue. It's a current snapshot of the software with a few more improvements than just the fix.
Updates from 6.10 are pretty simple. Read the section "Updates from 6.10" on this page:
Questions and comments welcome of course.
