Hi, @loudfan.
Thanks for your report and for sharing these helpful notes.
It looks like your SVG icon file is being served with a content type of ‘plain/text’, which could prevent the icons from loading correctly.

SVGs should be served as image/svg+xml. I recommend contacting your web host and pointing them to this thread. They should be able to correct this for you.
Thank you so much for the speedy response — I contacted the ISP and they made the change, so now the icons seem to be loading properly.

Excellent – your site looks great! Thanks for letting us know.
I’m having a similar issue but I’m not able to find that file on the Network tab of the devtools. I have access to the server, is there a way I can do this myself? Could you tell me how?
Thanks for your time,
Sergio

@sergio-cabral Sorry to miss this earlier. In case you still need help:
– There’s a step-by-step guide to finding the file in the network tab here so that you can check the type is correct: https://ww.wp.xz.cn/support/topic/blank-icons-sometimes/#post-8792546
– If the type is incorrect, you can follow this guide to resolve it (assumes your host uses Apache) or contact your web host.
If you don’t see the symbol-defs.svg file at all, it’s possible your site isn’t including it – you may need to clear all caches so the latest plugin files load.
Starting a new topic with a description of your issue and what you’ve tried so far is a good idea if you’d like further help with this.
