CMS Made Simple Forums

I'm having a weird problems with SEO Tools. It works fine otherwise but when I try to check "Automatically generate a page description where none is provided" box or any other checkbox it tells me that settings were succesfully updated, but they were not. The just stay as they were by default - "Generate standard Meta Tags" is checked, the others are not.

CMSMS is version 1.10.2 and SEO Tools 1.5

Can anyone provide some light to this issue?

Not all modules are compatible with 1.10.*...
