ISP3 novice needs help

Hi,
After months of great working with ISP3(I had some help) I did something really stupid.
My server is not fast and I tried to upgrade from php5.6 to php7.1 (so stupid) after that a empty screen.
Everything (3 webshops) still works but the ISP3 screen stays empty (see attached image)
The famous error: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20160303 /mysqli.so' which I can't find the 'easy' solution.
I'm Dutch so I hope someone can give me a understandable answer and don't be angry about this question, you can make me happy!!
Thanks,
Jos....

PS. This is the page I used to upgrade: https://www.howtoforge.com/tutorial...fig-3-from-debian-packages-on-debian-8-and-9/

 

Read the comments of that howto. There it is explained how to repair the broken system.

Choose PHP version that works with ISPConfig, 5.6 or 7.0.
Of course there may be something else that caused the problem.

 

Thanks, I didn't see these comments (sorry...)
Tested your two lines
Both stood on 0 (7.1) and now on 7.0, I tried also 5.6 ... (see image)
Still no ISP main-screen visible :>((

On the second image, I think I made, during the first installation, there a error, where can I find these settings(to check)?
Thanks again for helping me out.. :>))

 

Have You tried https://www.howtoforge.com/community/threads/please-read-before-posting.58408/

 

Yes, but it didn't work!!

 

Believe me, I tried it yesterday before asking for help...

 

Try the commands one by one.

Code:

wget -q -O htf-common-issues.php "http://gitplace.net/pixcept/ispconfig-tools/raw/stable/htf-common-issues.php" 

Then

Code:

php -q htf-common-issues.php

 

Sorry, still no information visible...

 

root@jos:/# locate htf_report.txt
root@jos:/#
Tried to locate the file, nothing...

 

Does the wget command download a file named htf-common-issues.php ? You should get the file or wget should complain about something.

 

No complain about wget, so he/se get the file, but then ....
Starting the line gives a few moments of silence (I think working) and after that no complaining.

 

What is the contents of that file? It should be a PHP script.

 

I can't see the the file itself, I can see it's doing something and then stops.
How can I make it visible? In my browser it gives a error (forbidden).

 

Look at the file htf-common-issues.php . What size is it? What is inside that file? Use the cat command, for example.

 

Both files are empty..

 

Did a new 'download' and opened the file... Empty ...

 

That explains why You get no result file.
Since that script can not be downloaded right now, try other ways to see what is wrong.
Is the operating system Debian? Version 8 or 9?
Verify web server is running. It may be Apache or Nginx, You have not written which. Check like this:

Code:

service apache2 status

Verify database is running, check like the web server test.
Read logs to see what makes errors or fails. Logs are in /var/log, and subdirectories thereof. Check /var/log/syslog first. Then do

Code:

ls -lht /var/log/ | head 

to see most recent log files and read those.

 

As far as I know Debian 9.
Apache is running (see image, was a long list, just the top)
All 3 webshops are up and running...
Second image shows the logfiles, I have to read them all??

 

At least read syslog php5-fpm.log. The first is useful to read for any problem, the latter may be useful in this case since the problem may be PHP related. If those don't help read all the most recent log files.

 

In the first post there was error message. Are there no error messages now?
If no idea emerges from reading log files, check all the PHP packages that are mentioned in Perfect Server guide for Debian Stretch are installed. (if the server is Stretch, verify that first with lsb_release -a )
