Hi, what version of Wordpress is it? What plugins are there?

The mysql_connect() function has been deprecated since php 5.5 and then completely removed since php 7.

Alehandro

Wordpress 6.0 like I say, seems to be mysqli addon not loaded in PHP8.
Plugins like WP All import pro, Wordfence and the All in one SEO plugin.

Alehandro
The above shows that you use mysql_connect php to install the mysqli extension by default
App store find php8.0 click on Setting and finally click on phpinfo to see

Like I say: [https://kepkuldes.com/images/098d8951b757ef6ed4258c9956f10216.jpg](https://)

Alehandro
reinstall php8.8

Alehandro

aaPanel_Kern
Uninstalling, please wait...
Are you sure to install PHP-8.0? Confirm
Finally there mysqli but can´t start it:

I clicked many times on start.

Check the logs for specific errors

Alehandro

aaPanel_Kern

Where? I think the aaPanel is easy to use for management, but needs more programing to run only PHP like the sites need.

Alehandro

aapanel is areplace the previous complex and numerous commands with a few clicks, and no matter what you do, you need some relevant knowledge.

Alehandro

aaPanel_Kern

Yes that find but:
There is currently no fpm log

and slow log:
There is currently no slow log

aaPanel_Kern

Alehandro
Is it normal to try restarting php8.8 on the server interface and then check the Logs?

Alehandro

aaPanel_Kern

Restarted many times and start many times. Old versions aaPanel no problem.
Again:
There is currently no fpm log

aaPanel_Kern

Alehandro
Can you take a screenshot? Is the log not fpm

Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
It is recommended to fill in the following
Post link:
SSH account password and port:
aapanel login link address and account password:

I can you send the panel logins, but the Google Cloud VPS with 2 security keys will be a little problem. I opening only from web browser what GC VPS give us:
