hi,
it looks like you are running vb 3.8.9

. vb 4.22 doesn't exist or do you mean 4.2.2

? I can definitely recommend vb 4.2.5 and use my diffs for PHP 7.3:

For Mobile Styles you may be able to use this service:

a current editor is also in work:

So update to vb 4.2.5 is not a problem and sustainable.
