Can't log in to web admin: "An error has happened during application run. See exception log ..."

OK, so having finally got past the "Segmentation fault" when trying to reindex (see other thread), the admin gave me a new system message on login. I don't have it copied down, but it was something to the effect that the Cache needed to be refreshed, and it provided a link to the place in the admin where it could be done.

 

At that page, there was a button to clear the cache. I clicked it. The screen went white and this message appears at the top:

 

"An error has happened during application run. See exception log for details. "

 

I can't get back into the admin at all. When I point my browser to it, I just get this message. Ditto trying to load the store.

 

I managed to find what I believe to be the exception log, in var/log/exception.log . Inside it there are 5 entries that occurred over a period of about 20 minutes, each of which has a stack trace. Here's the last entry, with my server details removed in the interest of my own security:

My main question: how do I get the site and admin access working again?

Re: Can't log in to web admin: "An error has happened during application run. See exception log

Never mind, I found my mistake. In the process of trying to fix the Segmentation fault issue as described in another thread, I mistakenly got it in my head that 7.1 was the right version of PHP. I can see now that it's 7.0.

 

I uninstalled and then reinstalled with 7.0 selected. I had to reindex, this time being careful to use PHP 7.0. And then I had to refresh one of the caches. But this time it worked without crashing the whole thing again.

 

So I finally appear to be up and running cleanly, with no system messages. This product is obviously not for beginners. But I'll keep plugging away.

Re: Can't log in to web admin: "An error has happened during application run. See exception log

Does anyone know what this means?

 


  [Exception]
  Deprecated Functionality: Function mcrypt_module_open() is deprecated in /h
  ome/[user]/public_html/[magento dir]/vendor/magento/framework/Encryption/Cry
  pt.php on line 54

It *looks* like the magento code is trying to use a deprecated function in the mcrypt module, no? But supposedly CE 2.1 is compatible with PHP 7.1. So why would the code be calling a deprecated function? Or is this possibly some PHP configuration issue?
