 * Hello guys,
    I’m trying your cache plugin and I like it very much, but I have
   an issue.
 * I noticed that I can’t see anymore the filters in my gallery (the plugin is Portfolio
   Filter Gallery Premium) and I noticed in the DevTools Console this error:
 * **DevTools failed to load SourceMap: Could not load content for _\*sitename\*_/
   wp-content/plugins/portfolio-filter-gallery-premium/css/bootstrap.css.map: HTTP
   error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE**
 * I looked in _Asset Optimizazion_ but there is no option checked for **awl-bootstrap-
   css — portfolio-filter-bootstrap.css**. Do you know what creates the problem 
   and how can I fix it?
 * Thank you very much.
 * PS: the website is under construction so I can’t provide a link to it

 * Hello [@byaconicus](https://wordpress.org/support/users/byaconicus/)
 * I hope you’re doing well!
 * Would you please temporarily deactivate Asset Optimization and see if this issue
   is resolved?
 * I’ve tested the [free](https://wordpress.org/plugins/portfolio-filter-gallery/)
   version of the plugin with Asset Optimization enable and the gallery is loadng.
 * If after deactivating Asset Optimization the issue will be fixed, please re-check
   the files and reset selected options
 * to make sure that any of them is not causing this issue.
 * Let us know how it went!
 * Kind regards,

 * Hello there.
 * I’ve done as you suggested and the issue is solved, which by the way was about
   the gallery filters disappearing, not the whole gallery.
 * Anyway, the problem was caused by _jquery-migrate.min.js_ being moved to the 
   footer. The reason I didn’t notice it before is that instead of resetting the
   options I did deactivate them one by one, but it seems that after selecting the
   footer position for that particular JS, simply deactivating that option won’t
   work, the issue will remain. While after resetting all of them with the provided
   tool worked.
 * Thank you for the help 🙂

 * Hello [@byaconicus](https://wordpress.org/support/users/byaconicus/)
 * I’m glad you’ve been able to resolve this. Moving jquery and jquery-migrate is
   indeed causing issues with most themes/plugins.
 * Here’s a recent guide we made around Asset Optimization in Advanced Mode that
   should help you on how to initially setup:
