Hello. Thank you for contacting the Toolset support.
First of all - After checking to debug information you shared with us, I found that you are using outdated Toolset plugins. We always recommend running your site with latest stable release plugin version.
We publish the Types 3.0 with the new many to many relationships and we have added the number of new features to this major release last year.
For now, you need to manually update the plugins.
*** Please make a FULL BACKUP of your database and website.***
- Deactivate and Delete all Toolset plugins from the plugins page
- Download the latest Toolset Types plugin and install and activate it:
=> https://toolset.com/account/downloads/
- Upload and activate Types plugin and then you are free to install and activate all other Toolset plugins.
I already tried that. Upgrading to the latest release gives me even more errors. On latest version I'm still unable to populate the file field and it also causes an error on the front-end and displays the URL instead of the Read More link
Well - we always recommend you to run your site with latest stable Toolset plugin as if you continue to use the outdated Toolset plugins, sooner or later it will cause the issues.
I also noticed that you are using outdated WordPress version as well, Can you please update WordPress to latest version.
Once you update the WordPress to the latest version, please feel free to share the problem URL and details about the issue and I will try to help you further.
I have set the next reply to private which means only you and I have access to it.
