First of all, have you tried changing the permalink of the post that’s giving you difficulty? Maybe the permalink is a conflict with something? The permalink is the URL of the post, and it’s usually set right below the title, pulling from the title. You can click edit next to it and edit the permalink.
If that doesn’t work try deactivating all your plugins and trying to publish the post. It could be a plugin conflict.
It could also be a corruption in your .htaccess file. This is a powerful file that can cause big issues for your site if corrupted or if wrong settings are added. It’s found in the “root” of you site, the same directory where you will find wp-admin & wp-content. You could try changing the name of .htaccess to “.htaccess-bak” — this will render it non-functional for your site — and then going to Settings — Permalinks and resaving your choice there (this controls how your urls for your site are automatically generated). Looking at your site, you will want to re-choose Post titles. WP will automatically regenerate an .htaccess.
Do fix the 403 issue before trying to deal with site slowness!
You can test the load time of your site here: https://tools.pingdom.com. You could test each of your posts so far to see if any one of them is causing the slowness. This could be due to an extra large image file, for instance.
You might also want to look for a caching plugin to help with site speed. For instance, https://www.ads-software.com/plugins/wp-super-cache/.
The site could also be slow because it’s getting a lot of traffic. (200K twitter followers is a lot of potential traffic!). Traffic can cause site slowness if you are on a low-cost shared hosting plan that doesn’t have a lot of bandwidth to help accommodate the traffic. Check your analytics to see if that’s potentially an issue.
