When trying to revise Theme Options a few days ago, I received this message instead of seeing the options: There has been a critical error on your website. Please check your site admin email inbox for instructions. I then received an email today from WordPress: WordPress caught an error with your theme, Local Business Pro Responsive Theme. Aside from this error, my website is working fine. I only noticed this because I was making some updates, which I haven't done in a few years, so I don'y know when this error started. I'm using Local Business Pro Responsive Theme, v1.7.6. I also have a child theme that I have activated. I noticed that there is a version 2.0.1 available. But a few years ago I tried to upgrade my theme and my site crashed as a result, so I'm nervous about installing the new version. Do you think the problem is related to my theme, or is it a compatibility problem with WordPress version 5.5.3, or PHP version 7.3.25? Also, I noticed a theme called Handyman - Home Repair Business WordPress Theme. What's the difference between the two themes? I've attached the email I received. Do you think upgrading will cause a problem?
