Tried to upgrade my vb 5.1.4 lately to the latest alpha 6 and got this error:

"Fatal error: Cannot redeclare class vB_dB_Assertor in /home/DFSDS/[url]/core/vb/db/assertor.php on line 18"

What's up with that?

Might check this thread to see if the OP's reply is the same issue you have.

Also google is your friend

[Mr.Danko Jones]

Thanks!

What does he mean by this?:

"- solved -

added missing entry "mysql" in core/install/config.php"

[Lynne]

He's talking about this line in your /core/includes/config.php file:
$config['Database']['dbtype'] = 'mysqli';

What does your line look like?

[Mr.Danko Jones]

I had it blank but changed it to 'mysqli' and now getting this:

"Critical Error

We are currently experiencing technical difficulties. Please check back in 24 hours."

[Lynne]

Then change it to just "mysql". It may be that your server doesn't have "mysqli" enabled.

[Mr.Danko Jones]

Neither seemed to fix the problem unfortunately.

[Paul M]

Enable debug mode on the frontend and you will get a proper error message instead of just the "Critical Error".

I'm posting this in this old thread since Google refers to it when googling the "Cannot declare class vB_dB_Assertor" error message.

This problem just happened to me too (on a local XAMPP install on Windows, with PHP 7.3.8 and MariaDB 10.4.6), and the solution above worked for me, i.e. to change:

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

to:

Block Disabled:      (Update License Status)
Suspended or Unlicensed Members Cannot View Code.

in the /core/includes/config.php file.

For some strange reason, the installer's first stage fails to fill in this value, which in turn cause this critical problem. Very strange?!
