Ok we apparently are running out of server space at our site and think that is the reason we are seeing a lot of irregularities.

we are down to something like 70mb free space.

Things are getting real strange at our site.
Is it a correct assumption that its simply because we are low in space?

Silly question I know, but we want to double check. We plan on upgrading soon.

Problems that are occuring are for example:
no left blocks on certain pages, no acces to some areas etc.

-Thanks!

Running low on disk space can result in odd behavior. Many applications create temporary files. For example, XOOPS creates temporary files in /templates_c and /cache. If those files cannot be created, the application may fail in unpredictable ways.
