When I upload an image i get the following error:
The file is not a valid file and cannot be deleted.
I’m working with MODX 3.0.1-pl
I was very confused about this message, because I don’t want to delete a file, I’d like to upload a file…
Now I found out, that no uppercase letters on the filename are allowed.
Can I achieve, that my file is uploaded anyway and uppercase letters are replaced with lowercase letters automatically?
Maybe there are plugins from other extras that run on the events “OnFileManagerBeforeUpload”, “OnFileManagerUpload” or “OnFileManagerFileRename” and possibly interfere?
Under cogwheel-icon → “System Settings” there is a tab “System Events” to check that. Use the event name in the search field, then check the column “Plugins”.
Does it make any difference if you change the value of the system setting upload_translit?
