Hi Clay,
Just a quick update to explain the workaround I found. I couldn’t open the database so was looking at having to redo s lot of work. However after reading something on the forum about exporting the site, I right clicked on the site and most of the options were greyed out including export, but there was an option to Clone the site. I gave that a whirl and the cloned site opened up fine. I just had to update the version of PHP it was running as it was throwing up an error message but other than that it was a very quick fix.
Hope this helps anyone else who runs into this issue.
