Hello Shahin,
1. Did not use Elementor for two months, so I’m not sure how long this issue is going on. I used several devices and get the same error. Every time i use Elementor the error occurs. The frontend looks like it should.
2. The error only occurs when using Elemtor. For exmaple when i write a new article. When i turn off the Ocean extra plugin elementor works fine.
3. https://pastebin.com/pYM3RksU
Experiments are turned off, cache is cleared.
Kind regards
Christian
