Error 408 on upgrade to 4.3.1

[Mercury]

Hi,

I've been doing several upgrades today, starting from 3.9.2 version.

Trying to upgrade from 4.2.7 to 4.3.1, an error (408) shows up, and no upgrade confirmation dialog window shows up....

Checked also the error_log file, but there's nothing showing up....

Any ideas?

Thanks.

Best regards,

Hi again,

I've tried to upgrade once again, but the same error shows up (408)....
I've found the following message in the error_log file:

[18-Jan-2018 12:00:10 UTC] PHP Fatal error: Class 'PDO' not found in /home/mercxjbr/public_html/espo/application/Espo/ORM/EntityManager.php on line 138

It has something to do with my issue?

Thanks!

Best regards,
Roberto Jobet

Hello
I saw such an issue here http://forum.espocrm.com/forum/insta...ying-to-update
Do you have other tables in database, are not created with crm?
