@MattyRob any idea mate what causes this peculiar behavior?
Seems like the $response is the problem which causes the null problem with $versions inside count().
I have confirmed my finding with the help of var_dump() and indeed it produces the same aforementioned 404 error while fetching it with wp_remote_get().
What confused me with the code snippet I shared above is this portion of code:
// Problems? Bail.
if (is_wp_error($response) || empty($response)) {
return;
}
The first part is supposedly catching the error here…but if we follow the code, we see
// Get decoded reponse.
$versions = json_decode(wp_remote_retrieve_body($response));
which by looking the implementation of wp_remote_retrieve_body(), we see also
Possibly because I activated redirections and sitemaps two days ago (I did this a long time ago, but had problems then too - then switched to manually creating the sitemap).
Now how can I disable redirections and/or sitemaps without access? I renamed the plugin via ftp, and then I can get into the backend - but if I rename the plugin again, I lose access again.
I activated the redirects and sitemaps in the plugin on two pages… they no longer work or only work when the plugin is deactivated.
On another page I have not activated the redirects and sitemaps… everything works correctly there (even if cpseo is otherwise activated…).
Is there a way to deactivate the redirects and/or sitemaps without access? I think that the other two pages would then work again… or is there a way to enable meta title and description somehow?
Thanks for help!

We are working on getting the API server back up and running - ran in to some major problems as the base software was very out of date. It seems the is causing the issue.
[Update] - the API is working again as far was we can test so this issue should resolve.
