When I went to Appearance on dashboard and then clicked on theme editor to update some files. However, when I tried to click ‘update’. The error message
“Something went wrong. Your change may not have been saved. Please try again. There is also a chance that you may need to manually fix and upload the file over FTP.” shows up.
I have tested every single plug-in. But, it doesn’t seem to have anything to do with the plug-in. The theme was built by a previous developer hired before me. So, could it possibly have something to do with the ownership or permission set by the previous programmer. If so, am I still able to upload the file over FTP?
