Problem With Accessing Theme Options

When I try and access the theme options via my dashboard I get this error message and can not make any changes or edits to the site

Dzonia Responsive Theme Pro Options
The site is experiencing technical difficulties. Please check your site admin email inbox for instructions.

Then this was the info sent via email:
Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with your theme, Dzonia Pro Responsive Theme.

First, visit your website (https://dinsdalecontracts.com/) and check for any visible issues. Next, visit the page where the error was caught (https://dinsdalecontracts.com/wp-admin/themes.php?page=optionsframework) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.

To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

The site looks fine and is still running but I can not make any edits or changes what so ever.
Any help would be much appreciated.

Hi! I am having the same difficulty. I just recently took over managing a WordPress site, and everything was horribly out of date. It hadn't been touched since 2016. I upgraded my PHP db to 7.4, my WordPress is now 5.3.2, and I cannot reach my theme options page. Unfortunately, since I inherited the page with D'Zonia Theme Pro, version 1.3... I wanted to upgrade that as well, but it was not purchased on my account, and I'm not getting the same kind of email that Craig got from his host, so I can't identify the exact lines of code that are causing the problem. Is there anything you can do to help?

Thank you!
Tom

 

I purchased the newest version, so I could have a functioning, supportable theme to work on. Thank you, Shamaela. I will be emailing you directly.
