Problems that have surfaced after upgrading to WordPress 5.0

We are now at version 5.0.3 with no improvement.

Aside from the universal problem of figuring out how to work with blocks (the documentation is abysmal), there were some plugin and user interface problems revealed.

The plugin WordPress Contact Forms by Cimatti gives these errors in the WP Health Check plugin report. I am not concerned about this plugin as Cimatti appears to have abandoned it and I will too.

Next issue: There are two plugins that if both activated create a problem with scrolling while in the editor. The affected plugins are MetaSlider and Slider by 10Web.

Neither slider is a problem unless both are activated so I really don’t know which to blame. Somehow, the main edit panel and the sidebar panel become interconnected in a way that prevents scrolling from the top to the bottom of the main panel. Scrolling stops before the lower or upper text of the document appears, depending where in the document you begin the scroll. This while using the main panel scroll. To get the rest of the way to the top or bottom it is necessary to scroll the sidebar window which also affects the main panel scroll bar.

This is difficult to explain so I’ve made a screen recording video of the problem and placed it in this post. The remedy is to deactivate one or the other of the plugins that create the problem.

In this video I have opened a lengthy document (more than one screen of information) in the block editor. The mouse pointer is in the editor panel. I begin to scroll the panel contents with the mouse wheel. The scrolling stops before I reach the bottom of the document. At that point I move the mouse pointer to the sidebar and begin scrolling there. Notice what happens to the scroll bar thumb in the sidebar – two appear and they overlap. I scroll up again in the sidebar and the main window scrolls but does not reach the top of the document. But it should not have been scrolling anyway. When I have run out of motion there I place the mouse pointer back in the editor panel and can finish scrolling to the top of the document. This same problem exists with or without the sidebar showing, and even if the scrollbar thumbs are dragged directly with the mouse.

This next problem is a UI issue. I don’t know if it is by design or a bug. The following images show how selecting any block editor view option prevents the mouse hover from drawing a frame around the hovered block. Deselecting the view options restores this frame. I would prefer to use the Top Toolbar option but not if it means losing the hover highlight of the blocks.

Next problem is while editing a document, using the Preview button produces a preview screen but new material is not seen. It will not show up in preview until after an Update is performed which kind of defeats the purpose of the preview. A related issues updates following a click on the Update button will frequently hang requiring abandoning the current screed. Symptoms are the Saving message blinks on and off endlessly. Sometimes it happens that the updates are seen when the document is visited, sometimes not, and there will very likely be a notice of a previous edit being found. I’m now going to update this document so I can see if it presents as I intended.

Jan 9 – updated to 5.0.3 and the Editor Preview option is still showing the page or post but not showing changes after editing a page or post. It is necessary to commit changes with the Update button then go look at the page or post to see if you got what you wanted. You probably realize that defeats the purpose of the Preview process.

The built-in text widget at WP 4.9.9 offered a Visual tab that allowed wysiwyg previewing of the widget contents. That is missing in 5.0.2 using the classic editor. I’m using the TwentySeventeen theme. Here is an example screen shot.

Second update and resolution found.

Continuing the analysis, I opened the widget page using the Customize menu rather than the Appearance->widget meny and discovered the Visual tab can be seen there.  Having discovered this unexpected on/off situation I removed moved groups of plugins from the plugins directory and found that by deleting the Advanced Rich Text Tools for Gutenberg plugin this Visual tab is restored regardless of which menu is selected. This is the first time I’ve run into a plugin problem that required removal vs disabling. So this issue is resolved.

Final note: Still not happy with the diagnosis, I re-installed the plugin and enabled it and the text widget Visual Tab disappeared again. I then disabled it and the tab was restored, so there is this remaining issue of deleting vs disabling the offending plugin, but since I’m not using the block editor it doesn’t need to be enabled or installed. I’ll leave it for now installed but disabled and keep this as an example of new experiences I’ve had since Bebo came knocking.

Here is the widget menu with the previously missing Visual tab.
