I have just now updated OJS 18.104.22.168 to 3.1.1-2. Due to recaptcha v1 problem, I decided to upgrade the software. Now, when logging with administrator or other user account, a blank page is shown for submissions page. Also it happens for Archive page.
My PHP version 5.6, installed on a web hosting service.
Can someone help to resolve this problem?
In error log, I found:
PHP Fatal error: Uncaught exception ‘PDOException’ with message ‘SQLSTATE[HY000]  No such file or directory’ in /home/ijapasco/domains/ijapas.org/public_html/lib/pkp/lib/vendor/illuminate/database/Illuminate/Database/Connectors/Connector.php:47
Hmmm… It seems like something is wrong with your PHP and DB connection in that library that OJS uses.
Do you use MySQL DB?
You could try to google after a solution – I found some possible reasons/solutions…
For example, to have the same socket files used in both:
a) Could you run this command: php -i | grep pdo
b) Then, could you see what is the socket variable for your MySQL DB?
but maybe also @NateWr or @kaschioudi could better help…
