I am trying to: Install types 3.4.7 on a server running wordpresss 5.7 and PHP 7.4.3

Link to a page where the issue can be seen: N/A

I expected to see: N/A

Instead, I got:

I recently migrated my site to a new server, then upgraded WordPress to 5.7. On the old server this site was using Types version 1.8. I did not include this old version of types in the migration because it is not compatible with WordPress 5.7 or PHP 7.4.3.

I downloaded Types 3.4.7 and attempted to install that. As soon as I click "activate" on Types I get this error: There has been a critical error on this website. Please check your site admin email inbox for instructions.

There are tables in my wordpres database that were created when Types version 1.8 was installed on the OLD server (see attached). I am not sure if this would be the cause of the critical error above. Please advise.

Hi Michael,

Thank you for getting.

IN order for us to understand what the exact error is you will need to enable the wordpress debugging and let us know what error is being printed out.

To enable the wordpress debugging, you will need to add the following to your wp-config.php file

define( 'WP_DEBUG', true );

Once you've done this please try activating the types plugin again and let me know what exactly the error is.

If you need some further details the wordpress debugging then you can go ahead and have a look at the article below.

Hi Michael,

Thank you for the information.

It would appear based on this error that the SimpleXML module is not enabled or isn't installed
What I would recommend is getting in touch with your host and ask them to enable this for you.

Having this module enabled should resolve the fatal error issue.

Thanks,
Shane
