Error when changing server

[Junghanseaten]

Hi everyone,

after a server change I have a few problems to get the page up and running again. Does anyone have a hint how to get it back to work? I'm grateful for every tip.

Many thanks for your help

The messages you get refer to your files and line numbers. We don't know what they contain, so hardly can help without more information.

You should take care of the fatal error first, to get it running again. size() is used for images. Make sure that all your files were transferred when you moved to another server. Make sure the CHMOD settings are valid/identical. 

Can you at least login to the backend? If so, install Tracy Debugger, which will give you further infos + tools for debugging.
