Re: pgAdmin 4 v1.3 fails to load

Dave,

Just to follow up your previous advice: I have done a complete uninstall of
the application, ensured
the installation directory is removed, then re-installed. I tried starting &
stopping pgAdmin 4 a few
times before re-booting & then again after re-booting my system.

In both cases, before & after re-booting, pgAdmin 4 loaded successfully
about 50% of the time &
didn't load in the other cases. In the unsuccessful load cases, most, but
not all, times there was an error msg.
"Error loading script". But the nominated script varied each time.

Thanks for your continuing investigations.

Kind regards,
Peter Johnson

I'm still struggling to reproduce the issues myself, but all the
evidence suggests it was the move from QtWekKit to QtWebEngine that
caused it (that happened in 1.2). We did that because of numerous
other bugs in QtWebKit, and because QtWebKit has been deprecated and
removed from current versions of Qt. Unfortunately it seems that
whilst QtWebEngine solves the original problems, it has it's own set.

We're currently trying a PoC with another option, as well as thinking
through some other ideas...

Apologies for the inconvenience in the meantime.
