I wish I could be of more help with this. You’re not the first one to report these 403 errors, so it seems that something is going on.
But so far, I have no idea what’s actually causing this. I haven’t been able to reproduce this issue, which makes it hard to really investigate this. Maybe some plugin or some theme or some setting or something else is causing this. But of course, that’s nowhere near enough to be able to fix anything.
The issue isn’t in the process of updating a page. My theme (the default wp-theme: Twenty Twenty-Four) has an option to “edit site.” This should open up a panel where you can edit the template for all sites. Before, I had added a navbar and footer to all the pages, but now I need to edit it so that my district can unblock this website.
The other problem, similar to mine, was fixed by clearing old cookies. However, this issue is related to Infinityfree or WordPress because on a different computer, the same issue is happening… even in incognito.
Ok, I have not resolved the issue, but I have accomplished my goal of editing the template. It took a lot of playing around, but after clicking the template and editing the correct one, it works!
Thank you all for your efforts and for trying to help me.
Have a good one!
