I am trying to: Update permalink settings.

Link to a page where the issue can be seen: hidden link

I expected to see: The Permalink Settings page.

Instead, I got: See screenshot.

In troubleshooting this issue, disabling the Types plugin resolves the issue.
This seems to be a problem with custom post types and WordPress class-wp-rewrite.php

Here is the debug info:

Hello. Thank you for contacting the Toolset support.

I review the debug information you shred with us and I found that you are using the PHP verion 8.4.19.

Toolset plugins are yet not fully compitible with PHP 8.4.x.

What if you try to downgrade the PHP version to PHP 8.2.x and check if that help you to resolve your issue.

[Thorworx]

I tested 8.3, 8.2, 8.1, and 8.0 - ALL return the fatal error.
Deactivating Types the error goes away... but when I re-activate Types, I'm getting 404 errors for my CPTs - which is why I was trying to update my Permalinks.

Fatal error: Uncaught TypeError: Unsupported operand types: string & int in /home/duboisking/public_html/new/wp/wp-includes/class-wp-rewrite.php:1036 Stack trace: #0 /home/duboisking/public_html/new/wp/wp-includes/class-wp-rewrite.php(1413): WP_Rewrite->generate_rewrite_rules() #1 /home/duboisking/public_html/new/wp/wp-includes/class-wp-rewrite.php(1513): WP_Rewrite->rewrite_rules() #2 /home/duboisking/public_html/new/wp/wp-includes/class-wp-rewrite.php(1888): WP_Rewrite->refresh_rewrite_rules() #3 /home/duboisking/public_html/new/wp/wp-includes/rewrite.php(282): WP_Rewrite->flush_rules() #4 /home/duboisking/public_html/new/wp/wp-admin/options-permalink.php(212): flush_rewrite_rules() #5 {main} thrown in /home/duboisking/public_html/new/wp/wp-includes/class-wp-rewrite.php on line 1036

That is really strange.

What if you try to deactivate all third-party plugins excluding Toolset plugins and then check if you able to see it working when ONLY Toolset plugins active.
- Do you see any difference?

[Thorworx]

NOTE: I downgraded to 7.4, and was able to access the Permalinks settings page with Types active.

However, a warning is still thrown:

Warning: A non-numeric value encountered in /home/duboisking/public_html/new/wp/wp-includes/class-wp-rewrite.php on line 1038

Disabling Types makes the warning go away. There is obviously a problem with strings/characters in my CPTs or taxonomies.
The warning does not display with debugging turned off in WP config.

[Thorworx]

Disabled all plugins except Types and Toolset Blocks.

Same result. Warning with 7.4, Fatal errors with 8.0 and up.

[Thorworx]

NOTE: When I tried to switch to Twenty-Twenty Five theme with Types enabled.. Fatal Error.
It DID switch themes. Disabled Types, and no errors switching themes.
