Hi,
I tried uploading multiple different types of images that fit the requirements, Still, I am not able to upload it, while uploading I always get an error that:

** Your upload failed because of a filename error. Filenames should be 100 characters or less (including the file extension) and avoid special characters (e.g., #, (), '). **

Please help me out.

This isn’t not in the right forum. This is sir layout help, not bugs. I’d recommend switching it or emailing support directly.
