FYI, I have the same exact issue with Astra/elementor. unable to put my favicon on site. In customize, there is no header builder => LOGO, nor no Site identity Option. Help!
I added WP-Optimize to address matters of caching. of course with my luck, it made the green pre-load stall altogether. So I uninstalled it. NOW, my new issue is once the form loads, I get to the payment page and hit the button, the button grays out, and does that way not moving at all.
Thank you for that. I will absolutely review the article you mentioned about caching. I did try on my cell and was having the same issue. Maybe you made some magic and all seem to go through smoothly on my desktop, NOW, lol. I will try cell once again.
I will also begin to put back some of my plugins checking all the way, I stripped it bare to see if there was a conflict with any of the other plugins. Thanks for the quick response.
