Are you utilizing the Instant Reload Add On? If so can you try disabling that?
If you’re still having trouble can you create a new, blank site in Local and access that okay?
If you can, then you may want to try reimporting the site getting the errors. The steps would look like this:
Locate the site files on your machine, and save a copy of them to your desktop. If you click Go to Site Folder under your site name it should take you right to where they are located.
Once you have those copied, completely delete the site from Local
I have Instant Reload instaled but not yet activated. Never used it.
I’ve created a new test site and it works (but only after restarting Local).
When I was going to delete the problematic one, I’ve tried to clone it first and it works. Done some tests and I think it’s all ok now. It wasn’t necessary to export and import as a new site.
