cannot upgrade standard modules

[benediktrunge]

Hey everyone,

I have a problem with updating the standard modules (newsletter, navigation, ..) on my Shop.

I made it now to update 2 of 4 Modules, with just starting everything new and giving it another try. Sometimes it works sometimes not.

And Sometimes a white screen appears wenn ich click something in the Back Office and sometimes I get a warning that this is an private Connection. Every time I load the back office new it works fine (until the next error comes or white screen appears,...)

I have a feeling that something with my Server (dedicated Server) isn't configured right, but I'm new to this and I absolutely have no clue what's wrong.

It would be great if somebody could help me.

 

(Uploading a Module works fine.)

 

Thank You

Kind regards,

Bene
