Looking at your site right now, it looks the same as it did last time. Which is to say that there are references to Gravity Forms in the HTML.

At the risk to trying your patience, could you double check that the Gravity Forms plugin is deactivated?

I’m assuming that this is a Single Site install of WordPress, not Multi-site (“Network”).

About the only thing left that I can think of is to deactivate all plugins except WP Forms, and change to the default Twenty Sixteen theme, and see if the problem still exists.

If site outage is an issue, you should clone the current site to someplace else as a test site using Duplicator or the Moving WordPress documentation in the Codex. And then deactivate other plugins and use the default Twenty Sixteen theme.

Anyway, the standard concept is to start out with “next to nothing” and gradually work your way up to the problem by adding one change (plugin or theme) at a time.

Also be sure that WP_DEBUG and WP_DEBUG_LOG are set to TRUE in wp-config.php during your testing. Be aware that messages may be generated that could corrupt the appearance of your site when you do this.

I should also mention that there are some pretty unusual situations that can cause what you are seeing, all to do with Redundancy somewhere in the web hosting setup. As in two web servers sharing the job of serving your domain, with one working from an out of date copy of the database. As I say, very unlikely.

The author of the plugin asks that you go to his site for help:
http://seo.uk.net/google-translate-widget/

I strongly suspect you are right about this being a Caching problem, but you seem to have forgotten about Web Browser caching, which this seems to be.

By the way, I see the form just fine on the page you mention, but it seems to be Gravity Forms, though I cannot be sure — I just see references to Gravity Forms in the HTML.

Now that I’m back at my desk, I’m confronted with some bad news: the plugin I used to use to safely use PHP is no longer in the Plugin Directory. And what I assumed might replace it does not seem to work anymore.

Both of these simplified the creation of Shortcodes, which are PHP code that is inserted into WordPress in a controlled way.

Any other approach to adding your own PHP code can just too easily cripple a WordPress site even when you have a good knowledge of PHP.

Without learning PHP, the only thing I can suggest is using this plugin to prevent future Posts from having no tags:
https://wordpress.org/plugins/require-post-tags/

Which still leaves you with the task of finding the current posts with no tags. For which I can offer no easy answer for you now.

I am sorry, but, as I stressed in a WordCamp presentation a few years back: you really need to learn PHP programming if you are going to do anything out of the ordinary in WordPress.

I couldn’t find any plugin that will delete untagged posts for you.

Someone who knows PHP could figure it out from this post: https://wordpress.org/support/topic/how-can-i-list-all-the-posts-that-have-0-tags?replies=5

If you want someone to write it for you for free, and don’t have any luck here, you might try http://stackoverflow.com

I, too, use a Ubuntu VPS for my low traffic WordPress sites. There is a bunch of stuff I had to do to get .htaccess working properly. Permalinks other than the query type will not work in Linux without .htaccess.

I’ll respond again when I dig up the documentation I wrote for myself when I last had to solve this problem.

Unfortunately, Support forum rules do not allow such specific discussions of hosting because the threads get spammed really badly.

However, I am willing to discuss this off-line if you contact me at [Link redacted]
