 * Hi folks,
 * meta silder now shows me this when I enter the meta slider command center:
 * ReferenceError: server_fp is not defined (video_cache.js)
 * All slideshows are still displayed correctly on the website itself, but not in
   the command center.
 * Do you have an idea what might be wrong?
 * Thank you very much for your help!

 * Hi,
 * This issue might be caused by another plugin/theme. So, please try to deactivate
   all your plugins except for MetaSlider and switch your theme temporarily to Twenty-
   Twenty One. If this fixes your MetaSlider issue, you can then try to activate
   all the plugins back one-by-one until you find which of the plugin is causing
   the conflict.

 * We haven’t heard back from you in a while, so I’m going to mark this as resolved–
