I was in the process of running the upgrade script from the latest forum (my version was a number of versions behind) and after the script was ran, I now get this message.  Can anyone point in the direction/give guidance. Thanks in advance.

Undefined constant 'IPS\HTMLENTITIES'

What’s the full stack of the error? That’s either caused by a 3rd party script or custom theme.

On the main site (just the index page)....I get the below:

An error occurred (500 Error)

We're sorry, but a temporary technical error has occurred which means we cannot display this site right now.

You can try again by clicking the button below, or try again later.

Try again

On the upgrade section, I get the following:

Thank you - I just posted the errors.  I am not aware of any 3rd party script I am running (only thing I have on my site at all unique would be google adsense script).  I had customized buttons on my site but was using standard themes.  

I had never used the easy upgrade option before (i.e., the button in the admin panel) and I'm slightly worried I totally botched everything.  I had last upgraded my forum in April 2018 (so basically 1.5 years since my last upgrade).

To give a bit more color, I am looking to upgrade from version 4.2.9. Is this too old of a version that I shouldn't use the standard "upgrade' script?  I at least had my back-ups so I have restored.

So how did you manage to resolve the issue?
