I gotten this error using MB Testimonials, it is showing in the console log https://prnt.sc/ITkLFT8pyiop, deactivating MB Testimonials Plugin the error gotten away. Based on the console log it seems like there is a blocking on the SVG. May I know how can I solve this?
Can you please share your site URL where I can see the issue? It looks related to the arrow next/prev of the slider. You can try to disable the arrow or use the custom arrow and check this issue again.
