I often get an error message when trying to save or publish a page. The internet seems to be working for everything else when it pops up, so I'm not convinced that the issue is on my end. How do I fix it?
I found this on the internet. Not sure it applies to you, but maybe it will help. It appears to be a Windows error, so you are probably using a Windows OS. I am a MAC girl myself, so I am not sure where you would find these things in the instructions, but if you don't see a result, try Googling it yourself to find an appropriate answer. "Code 0x01" The error indicates that there is a problem accessing the Windows temporary folder. ... If it is the case that you don't have full read write access or the path doesn't exist, resolving the issue using standard windows explorer UI should resolve error 0x01."
I recommend trying to publish from the File Manager instead of using the Publish button. You do have a large number of pages on your site, so this will help the builder not have to process through as much to publish it.
