Aggregate & Compress CSS / JS Kills Metatag Fieldsets I had to turn on aggregate and compress CSS and JS for my site as the performance was terrible and I was getting a lot of CSS errors (admin bar would disappear intermittently or not load correctly or other CSS errors)

Activating the aggregation improved page load times dramatically and solved all my other CSS issues, however, now I get an error with the metatag module in which the field sets for Open Graph, Facebook etc. won't load as hyperlinks which can be expanded, only plain text.

The issue seems limited to the blog content type.

Any ideas where I can look to solve the issue?
Most likely there is a parse error in a JS and or CSS file. Check the console for any error; fix them and try again.
