error: Your PHP installation appears to be missing the MySQL extension which is required by WordPress.

[lsepolis]

I had:
PHP Version 7.4.33 and WordPress 5.9.5
Updated WP 6.1.1
>>>
Updated to PHP 8.0.25
Success: Successfully applied PHP version “PHP 8.0 (ea-php80)” to the selected domain.
>>>
PHP Version 8.0.25
>>>
I have gone to the WP home Blog home page and:
Your PHP installation appears to be missing the MySQL extension which is required by WordPress.
Reverted to PHP Version 7.4.33
then all back, all OK
Where is the problem?

Is the screenshot attached of any help?

No, you must select "Currently Installed Packages" -> Customize.

 

[kodeslogic]

Go for Currently Installed Packages >> Customize >> PHP extensions >> php80-php-mysqlnd

 

[Leonidas Savvides]

Go for Currently Installed Packages >> Customize >> PHP extensions >> php80-php-mysqlnd

I installed the php80-php-mysqlnd success...

well???

 

[kodeslogic]

Do you see any errors in the error_log file?

 

[Leonidas Savvides]

What log file is this in the WHM or the cPanel or the Wordpress log file? And How and Where find this?

 

[kodeslogic]

Website error_log file is located at:

/home/USERNAME/public_html/error_log

 

[quietFinn]

There is also another PHP error log in the wp-admin directory, worth checking.

 

[Leonidas Savvides]

I have tried this today in the morning...
So, look for today’s logs...
Are they safe to share these files.txt as they are here, in the forums - in other words, are free of passwords?

 

[quietFinn]

There are no passwords in error logs.

Those logs can be big, no need to show more than like 50 last lines.

soon the:
/home/USERNAME/public_html/error_log
because needs admin permissions

can you make any conclusion?

 

[quietFinn]

Seems RPX_Widget is not compatible with PHP 8.

 

[Leonidas Savvides]

The RPX_Widget,
Probably is a Wordpress plug-in
So, can deactivate and retry?

 

[kodeslogic]

Yes, try disabling that plugin.

 

[Leonidas Savvides]

same symptom - after disabled

after installing MySQL plugin from 8.0 PHP -- is it need Apache restart???

Another issue the: error_log is huge in size, what to do...?
2
How do view log lines of error_log - log file in between:
06-Dec-2022 08:30---06-Dec-2022 08:50...?

[[email protected] blog]# pwd
/home/ lscom/public_html/blog
[[email protected] blog]# ls -la | grep error_log
-rw-r--r-- 1 lscom lscom 639505787 Dec 7 22:57 error_log
[[email protected] blog]#

 

[quietFinn]

tail -n 100 error_log shows 100 last lines of error_log

In fact you can delete the file, and try again, and get the errors in the log file.

 

[Leonidas Savvides]

Temp
Can I rename this log file, so as the system: LAMP CentOS Apache PHP MySQL WordPress

creates a new log file auto?
And view this new file,... after some time
Then, can delete the huge Logs file ...

well?
