Tag Div Composer not loading

I have been working on a wordpress site using newspaper theme. It is under maintenance mode until its ready to go live.

It had been working normally until about a week ago – when TAG DIV composer stopped loading suddenly – meaning I can no longer open the visual editor to make changes and it did not save the site properly. The main header and menu has disappeared and there are a few unfinished elements on the home page that needed adjusting.

TAG DIV seems to work properly on some of the sub pages – but not on the home page and not when I try to add a new page.

I have been in touch with my host provider who have ensured the settings are as per required for Newspaper theme., and they migrated the site to Managed VPS – but the problem still persists.

They found an error in the error log which could be an answer to the issue.

Thanks for your time on the phone.

As discussed, we were unable to find a solution to the composer plugin issue, however we did notice some PHP warnings/notices potentially related to the td composer that might be worth following up with the plugin creator.

Here is the output of the last entry in the error log:

We did try disabling all of the plugins, clearing cache, and replacing .htaccess with default. We also ensured that base64_decode was already enabled.

Please check with the plugin creator if they have other possible ideas and let us know if we can be of further assistance.
