After updating, Theme Panel shows errors

Hi,

I’ve recently updated to the new version 7.3, but some options in the Theme panel don’t work now.
This is what’s happening: http://image.prntscr.com/image/1c06c6a3c67c46fbb385563c98d1a824.png

I’ve updated to the new version by replacing the old wp-content/themes/Newspaper folder with the new Newspaper fodler from zip, as explained here, method A: https://forum.tagdiv.com/how-to-update-the-theme-2/

Any ideia?
Thank you.

This is solved.

If someone comes across this problem in the future, I’ll explain what I did:

Before updating to the new version I backed up the db. For some reason the update (or some option I missclicked) changed the url from “localhost” to “www.localhost”, which contaminated the whole db.

I had to export the entire data from the db to a txt file, replace “www.localhost” to “localhost”, delete and create a new db with the same name and import the whole data from the txt file.
All works now, every option in the Theme panel is visible.

Why I use localhost as url? This is an offline test server.
Thanks

Please ignore my previous post. Unfortunately this issue is still not resolved.

I was using http://www.site.com with Newspaper theme version 6.7 and wordpress 4.4.2

I updated the wordpress to 4.5.3 and theme to 7.3

Everything works fine, unless some configuration options in the theme panel: http://image.prntscr.com/image/1c06c6a3c67c46fbb385563c98d1a824.png

If I change the url to http://site.com (without the www), I can access everything in the theme panel, but I would prefer to use the www in the url.
Any ideas?
Thank you.

Hello,

I even tried reinstalling everything again: wordpress + Db + Newspaper + plugins
I was able to narrow the problem to a single plugin: All in one wp security & firewall

When I have this plugin active, some theme panel options are not shown, like in the image above.
Even with the plugin active but with no configuration (just the install), the error persists.
When I deactivate this plugin, everything works, no matter if I use http://www.site.com or just site.com

I already made a clean install of this plugin, but seems that it’s during the install process that it conflits with the theme panel. The obvious option would be to not use this plugin, but it’s kind of annoying because everything was working before the theme update and this plugin gives me important information that I wouldn’t like to not have.
Any ideas of what I can try next?

Thank you!
