General ⇒ How to solve invisible error?

[axelh]

Hi,

Sorry for the strange subject.

I am writing my PhD thesis with TexnicCenter. Everything was going fine, but since a few days I get a build error at a line which is completely empty!!! I have no idea why this might happen.

I attach an image of the error, which indicates an "Undefined control sequence".

Does anybody have an explanation, workaround, similar experiences ?

THANK YOU for any help!!

Hi Axel,

it seems that the macro \dcapprovalbaffil is unknown. This macro is used by a package or class, but you didn't mention your class and the used packages. Probably the problem could be easily solved if you provide a minimal example.

Looks very much as if something is up with \maketitle. Usually, this points to bad meta-data (\author, \title, etc.) or a badly modified \maketitle macro. You'll need to make and post a minimal example so we can have a bit more information.

Hi,

Stefan_K: you were right, \dcapprovalbaffil was not properly defined! Sorry, I did not manage to get this info out of the error message, which was a bit cryptic.

Thank you both in any case, now my thesis is error-free again!
