Hello, @seanh,
Thanks for providing the Login details, I have just logged in to your site and found the error when saving the theme options, please refer to this screenshot: https://postimg.cc/vcF2Gthv
First of all, you should have to solve this error and then apply the changes from the theme options.
Most of the time that issue is because of your server, It turns out the issue is that trying to save changes in the Porto Theme Settings is triggering ModSec rule 300015 for some reason, which is an SQL injection protection rule, so you have to disable this rule server-wide until you are in the development process, as the ModSec rule that was getting triggered is one of the standard WHM/cPanel rules as of one of the newer versions, so more and more servers are going to have this rule enabled by default.
So please contact your hosting provider and ask to solve it for you on your site.
Best Regards,
PThemes Team.
