I have been working on open cart perfectly and just about now I found out I can not upload an avatar or products image(s) via my front end, I can upload or edit products images from back-end for sellers. When a customer from front end tries to upload an avatar or product files, an error message of "File upload error" comes up after a few seconds. Please can someone walk me through on where to verify if the codes are okay?
I did check my host folders (permissions are granted to 0755) I even tried 777 and other tutorial I found on Google search .. but all to no avail.
