Multi-site network crashes and network crashes (white screen)
al3ilm (@ al3ilm)
I have a multi-site network:
https://al3ilm.com
They worked well
In December 2018 Apache occurred:
Apache 2.4.39
MySQL 5.7.25
It continued to work well
During March 2019, sometimes a white screen appears in Firefox and Chrome displays an error message that reads:
This page can not work al3ilm.com can not process this request at this time.
HTTP ERROR 500
Fortunately that problem goes away once the page is updated.
Then four days before you update to:
php 7.2.39
Then the site worked well
Then I raised the wp-rocket extension and got a problem with W3 Total Cache
The site crashes the same as the previous problem and unfortunately this time did not benefit the update page.
I made several solutions and did not succeed:
1. Upload files for WordPress version 5.1.1.
2 – used to repair the database in cpanel
3 – deleted the database and prepared and created a new user name and password and added to the file wp-config.php.
4. All add-ons have been disabled.
5. Rename the .htaccess file and save the permanent links to create a new file.
After the failure continued with the support of hosting they stopped the network by editing in the file wp-config.php:
define (‘MULTISITE’, false);
Only the main site works, the sub-stations do not work and the Web site list does not appear in the WordPress control panel.
I went back to the hosting and they asked me to display my problem on a WordPress expert and gave me the following error message to view it:
