 * Hi [@glenwpcoder](https://wordpress.org/support/users/glenwpcoder/), i have disabled
   my redis cache and still have the same issue. When i pick the default option 
   in my menu i can upload files and submit the form, when i choose the second option,
   the uploads works, but I need to upload an additional file in order to be able
   to submit the form. This behaviour seems to vary, but genrally it seems that 
   the validation javascript from Drag and drop somehow brakes. Hope that helps

 * Hi [@glenwpcoder](https://wordpress.org/support/users/glenwpcoder/),
    could you
   direct me to a tutorial how to clear the cache?
 * I tried the upload while logged off. I do not get the server error limit any 
   more, but the form would not submit. For some reason the upload function does
   not register that i have uploaded a file and blocks the form submission. Once
   i re-upload the file the form can be submited. What is even weirder ist that 
   this happens even for the field if it is marked as optional (no *).
 * Could it be that this not cache issue but a problem with the Plugin “Conditional
   Fields for Contact Form 7”. One of my options require to upload at least 1 file
   and for the other upload is optional.
 * Thanks for your help.
