Which forums are you using?
Sorry, I don't understand what you mean by "1.0 Forums" - I've only been here a couple of years
If you're using the one of the newbb/cbb family (/newbb in the /modules directory) then upgrade to CBB3.08 (from xoopsforge.com). All you need to do is delete the current module's files from the /modules directory, upload the CBB3.08 module and then refresh the module in modules admin.
CBB 3.08 uses the Frameworks and xoopseditor packages and you can also get these from xoopsforge.com
What other modules are you using? It would help others if you could say which modules work and which have issues.
Many thanks
