Migrate from Rank Math to SEOPress (big site)

Hi,

try to enable WP DEBUG first:

https://www.seopress.org/support/guides/wp_debug-enable-error-logging-in-wordpress/

Then run the migration.

You should see an error in the debug.log file.

[06-Jun-2023 20:30:20 UTC] PHP Fatal error:  Uncaught TypeError: in_array(): Argument #2 ($haystack) must be of type array, string given in /var/www/site.name/data/www/site.name/wp-content/plugins/wp-seopress/src/Actions/Admin/Importer/RankMath.php:136

That’s weird, this error means you have a post meta with this key “rank_math_robots” that is a string and not an array.

We’ll add a check to prevent this in a future update.

The fix will be pushed with version 6.7.1 of SEOPress Free.

How soon will the update be done?

In few days, maybe 1 week.

Thank you. I will complete the information and change the status of the request myself, if there are no more problems with the migration.

After migration, there are problems with adding posts to sitemap.
How to fix it: you need to go into the post and just update, no need to make any changes to the post
