Hey @Robin,
Thanks for reaching out!
Caching plugins in general can often cause issues like the one you describe here. This is quite a bummer, but there is one thing you can try to be able to use both plugins without issue:
• Check out the W3 Total Cache settings and see if there are settings related to “script minification” or “stylesheet minification”. If so, deactivate/disable everything minification-related that you can.
If this does not help, then unfortunately the plugins may be inherently incompatible on your site 🙁
Let me know what you find!
