Website URL ( http://hire.mrtech.pt/wp-json/wp/v2/types/post?context=edit ) Error Message The REST API is one way that WordPress and other applications communicate with the server. For example, the block editor screen relies on the REST API to display and save your posts and pages. When testing the R…

Clean install either uploading the wordpress myself or using the script installer. Without any plugin active or any new theme beside the default still have the same problem. I do not have any plugin/extension in the browser but yes, i tried using other browser including the smartphone. Still same pr…

I cannot publish or edit/save anything.

I’m 99% certain that the rest API is blocked by the security system: [image] Browser Security System - Features and Limitations Websites and PHP InfinityFree uses a security system on all free hosting accounts to ensure your website is accessed by real web bro…

[image] MrMorcego: I think some kind of firewall is blocking the URL of the Rest API. I strongly doubt that. It shouldn’t be. The article shared above specifically states the following: [image] Browser Security System - Features and Limitations What still works normally The security syst…

I strongly belive is what I said because I install classic editor and everything works fine again. And block editors dont work at all. But the same website files and code in other enviroments like dev and another production for testing works 100% normally. I will change hosting provider.

Out of intrest, what plugin\plugins are you using that don’t seem to be working? Elementor for example is known to have some problems because of its heavy resource usage.

After I investigate the problem the wordpress team say’s must be a firewall rule from the hosting company. Because block editors and some other part’s of the wordpress, like posting a page, a…

If it’s a clean install of wordpress with no plugins, then it’s not a hosting problem. Many people (myself included) run wordpress sites without issues. It could be that your networks firewall or a browser plugin is causing problems? Although I’ve not got the experience to say for sure

I can understand you wanting to move, and I wish you the best of luck with your new provider. Whatever is causing the problems you’re facing, I hope it works properly for you with the new provider

Since the issue was closed (not resolved), the following is for educational purposes and future reference. I did try Google and this issue seems to be persistent for years. Even in Wordpress forums! And there is no single consensus about the solution, some threads were left without a solution. But I…
