Site suddenly gives error

I am back from vacation.
And when i tried to go to the site...i get a error:
http://www.liufamily.nl/Mimi%26Arjan/

i didnt changed anything...

how is this possible?

login to the manager and disable the quickedit plugin and module.

but how did this happen?
cant i ever use quickedit again?

i have disabled it...and it still doenst work.

i clicked on Quickedit module, and checked: Module disabled
did i do this correct?

You need to disable the plugin as well. You probably will want to reupload the quickedit files, it seems like it cannot find one for some reason.

wtf...
i have deleted all modx files + deleted all the tables in database

upload everything again with a new insttall....

and i get the same error

Did your host upgrade or change anything about the server while you were gone?

yes, they updated the PHP to a newer version..
but that shoudnt be a problem?
i installed everything to a new dir and made a new database and stuff...

even when i installed it and view the sample site it doesnt work...

They clearly broke (or drastically changed) something with PHP configuration. Time to start asking them questions I think.
