Hmm those aren’t what I’m looking for.
When you say you can’t open/edit your website, do you mean you can’t open the project file at all? Or can you open the project file, but you just can’t preview the pages in RapidWeaver or in your web browser?
The lines I’m looking for in that Contents.plist file are:
<key>autoStartWebServer</key>
<false/>
<key>overrideWebServerPort</key>
<integer>0</integer>
And this is only if you can’t open the project file at all. The above is like a more technical version of this Preview function not rendering in Classic 9.3.4 9 [Solved] in the event you can’t open your projetct file.
If you can post some screenshots of the error you are seeing that might help too.
EDIT: Also always try restarting your Mac, that’s usually a first step to troubleshoot.
