Answers.Body: <p>Neither PHP 7.3 nor MySQL 8.0 are currently supported.  Looking at <a href="https://docs.civicrm.org/sysadmin/en/latest/requirements/" rel="nofollow noreferrer">system requirements</a> I see a minimum but not maximum version of MySQL; that needs correcting.  PHP 7.3 generally works but it's not part of the automated testing matrix as of now.</p>

Answers.Text: this error also occurs with PHP7.2.   I have the same problem with Wordpress 5.1.1 (or 5.2.1) PHP7.2 (Debian 9 Apache2) and MySQL 8.0.11.  The database is also correctly initialised.  I will try with a lower version of MySQL and report back.
  p.s. I tried with both CiviCRM 5.14 and 5.16-alpha1

Answers.Body: <p>I also see this error, using WP 5.2.2/MySQL 5.6 (recommended)/PHP 7.2 (recommended)/Apache 2.4/ on Windows 10, going back to Civicrm 5.5 (5.05) where updates to the Option Groups Admin UI were made(<a href="https://github.com/civicrm/civicrm-core/blob/5.5/release-notes/5.5.0.md" rel="nofollow noreferrer">https://github.com/civicrm/civicrm-core/blob/5.5/release-notes/5.5.0.md</a>) In the stack trace above you see refs to option group language members.
    Civicrm 5.40 does not have this problem.<br>
    As noted above, if you comment-out/remove Civicrm DSN in civicrm_settings, you can get back into WP admin to disable Civi plugin.
   On Windows 7 with MySQL 5.5 this error does not show up, I can install Civicrm 5.15 no problem.</p>

Title: Fresh install, Civicrm Wordpress, bricks admin
ThreadText: # Fresh install, Civicrm Wordpress, bricks admin
  
  (Asked by: username_0 on 2019-05-23)
  
  I'm having trouble installing CiviCRM. I can activate the plugin, enter the database credentials (tested via command line, and the app does connect and create the tables and what not). I hit the install button, and it does some work, then shows me a type of confirmation screen for a few seconds, but then redirects to
  
  /wp-admin/options-general.php?page=civicrm-install
  
  And in the browser says: "The site is experiencing technical difficulties. Please check your site admin email inbox for instructions."
  
  The error stack trace at bottom of this post. Snippets here:
  
  Looks like the fatal error is "Uncaught Error: Call to undefined function set\_current\_screen()"
  
  but the cause underlying it is more related to #4 /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/civicrm/civicrm/packages/DB.php(984): PEAR\_Error->\_\_construct('DB Error: synta...', -2, 16, Array, '\nSELECT v.labe...')\n
  
  which is at a higher level run by
  `CiviCRM_For_WordPress->initialize()\n
  CiviCRM_For_WordPress->register_hooks_clean_urls()\n
  CiviCRM_For_WordPress->register_hooks_common()\n`
  
  And, I see the browser error on any wp-admin page I go to. So it kinda bricks the whole admin.
  
  When I go to the public facing wordpress homepage, I get simpler error in the error log:
  
  AH01071: Got error 'PHP message: PHP Fatal error: Uncaught CRM\_Core\_Exception: [0: Transaction integrity error: Expected to find active frame\n\n thrown in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/civicrm/civicrm/Civi/Core/Transaction/Manager.php on line 107'

  Neither PHP 7.3 nor MySQL 8.0 are currently supported. Looking at [system requirements](https://docs.civicrm.org/sysadmin/en/latest/requirements/) I see a minimum but not maximum version of MySQL; that needs correcting. PHP 7.3 generally works but it's not part of the automated testing matrix as of now.

  > **username_3**: this error also occurs with PHP7.2.   I have the same problem with Wordpress 5.1.1 (or 5.2.1) PHP7.2 (Debian 9 Apache2) and MySQL 8.0.11.  The database is also correctly initialised.  I will try with a lower version of MySQL and report back. p.s. I tried with both CiviCRM 5.14 and 5.16-alpha1

  I also see this error, using WP 5.2.2/MySQL 5.6 (recommended)/PHP 7.2 (recommended)/Apache 2.4/ on Windows 10, going back to Civicrm 5.5 (5.05) where updates to the Option Groups Admin UI were made(<https://github.com/civicrm/civicrm-core/blob/5.5/release-notes/5.5.0.md>) In the stack trace above you see refs to option group language members.
  Civicrm 5.40 does not have this problem.  
  As noted above, if you comment-out/remove Civicrm DSN in civicrm\_settings, you can get back into WP admin to disable Civi plugin.
  On Windows 7 with MySQL 5.5 this error does not show up, I can install Civicrm 5.15 no problem.
