I am able to edit any page, except those containing the template named MainObjTemplate, which is not implemented by vbWiki.

Could you confirm this to be the case?

It's not only for pages containing the MainObjTemplate, try to create a arbitrary new page, containing only the text "This is a test" or whatever, and it will happen too (it happens when you save the page, as usual, you can still load the page later).

Also, as soon as I disable the vbWiki extension, the errors are completely gone, so it sounds strange that the errors would be in another extension too, don't you think?

Are there perhaps some error logs or something that would help you?
