Issue: Error with php 7.4.2 and VW 4.1 Beta 4 Build 5

The earliest VaultWiki versions designed to be compatible with PHP 7.4 are:
- 4.0.28
- 4.1.0 RC 1

Since you are using XenForo 2.1, we recommend upgrading to 4.1.0 RC 1, especially if you need PHP 7.4 support.

OK, thanks for the update. I hadn't seen 4.1.0 RC1 on the download section of this site at the time I posted this report. However, as of this morning, I am seeing it and have downloaded it. And I will send in a renewal before my license expires later this month.

I downloaded and installed RC 1 per the new download, and everything installed successfully. This is using php 7.3.14, on XenForo 2.1.7.

Couple of things:

First, I am not seeing the "Wiki" button in the top navigation bar, like I had with the previous versions. Wiki content is still available through another link I have down in the sub-forum list, but the "Wiki" button is not in the top nav bar like it used to be.

Second, I had a BUNCH of these errors thrown when I accessed the Wiki:

For the discussion messages, please make the following edit to src/addons/vw/vw/_core/model/ui/tab/discussion/vw.php. Find:
Replace with:
As for the wiki tab not appearing, I didn't have that issue on any of the sites I upgraded, but if you can still access the wiki then perhaps the tab got disabled. Check AdminCP > Setup > Public navigation.
It is also possible that the wiki was disabled in Setup > Options > VaultWiki: Site config > Wiki active now or recently. In this case, if it is not already active, do so now. Then run the following MySQL query:

I did all of the above -- edited the file.

Then checked the Public Nav page in the AdminCP, as well as the Site Config->Wiki in Setup.

All were checked/enabled.

Performed the MySQL query.

All is good now. Wiki button appears in top nav bar. No errors generated upon accessing the Wiki. It appears that everything is OK.

Another error received, just one time though. Appears to be VW related?:
