Almost everything I do in the manager of my website in MODX, I keep getting this error:

```
Unexpected token <:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@(mydomain).com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

```

I can not edit my website with MODX or do anything with this. Does anyone have any fixes or suggestions to fix this?

Thank you, any help is greatly appreciated!
