Avia Layout Builder not loading on one page

Hello

I have had this problem on my own website for a few months now, but it has also become an issue today on one of my client’s websites.

After creating a new page and publishing it I viewed the page, then when I go back in to edit it the Avia Layout Builder does not load making it impossible to edit the content.

The new page was created in the same format / style as other pages on the site. I deleted the page and created a new page with the same content – but still the same problem. Then I created another page this time with different information and the problem did not occur – I am able to edit this page. I am wondering if the problem is with the content on the page? It is a page with information about being an executor of an estate – the website is for a funeral home.

When the issue happened the site was running Enfold 4.8.6 – so I thought I would update to Enfold 5.1.2 but then things got weirder. I received the error message shown below along with a few other lines of error messages. Unfortunately I didn’t copy all the other error lines and now the message is no longer showing.

Notice: Undefined index: advanced_styling in /home/brisba65/public_html/wp-content/themes/enfold/includes/admin/helper-compat-update.php on line 830

I clicked onto the All Pages section to find that the page on ‘being an executor’ was no longer there! Somehow it has been deleted. The other new page I created is still there though.

In the private content I have included a link to my clients website, the other new page that is working and also the content that was put onto the page that has been deleted. I am wondering if the content has a trigger in it that is causing the issue?

Hopefully you can help as this page will need to be added again. If you need login details just let me know.

Thank you
