Internal Server Error IONOS

[till_mementor (Till Mattausch)]

Hi, I tried to install + activate matomo on a IONOS Wordpress Server. I get

"Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at to inform them of the time this error occurred, and the actions you performed just before this error.
More information about this error may be available in the server error log."

for every site. So matomo “crashes” my whole Wordpress Website. I can just revert it by deleting the matomo plugin folder via sftp.

debug log says:

What i tried:

• Installing matomo 4.13.5 (which works good on another Website from us at a different hoster) → same Problem
• Deactivating the IONOS Cache → Seems to kinda work but wordpress gets really really slow and some links don`t seem to work anymore
• added max_input_time = 600 / max_execution_time = 600 to php.ini → no changes

Interesting Links:

• Matomo doesn't work - #5 by heurteph-ei → Had the same problem with strato with some “boost” mechanic. I don’t know if IONOS uses this.

Interesting:
If I click refresh in my browser for 5 to 10 times the website gets displayed correctly without an error. Matomo seems to make my wordpress really slow. Maybe something runs into a timeout or it’s a caching thing?

atm Im wating on a call from IONOS to get the error log.

Hi @till_mementor, @Susanne
As thiis concerns a bug on WP plugin, I suggest you create a ticket at:

Build software better, together

[till_mementor (Till Mattausch)]

Hi, we are now using Matomo cloud and connect it to our WP-Site with an third party plugin from the WP-Store. Not ideal but it works.

[alexander-simon]

Dear All,
I ran into similar issues: Managed WordPress by IONOS; after installing and activating the WP Plugin, it appeared that my whole WP site was down (internal server errors).

With some patience and several reloads, I entered the Plugin directory and deactivated the Matomo WP Plugin. Now everything is back to normal.

I am going to uninstall the Plugin and try the Matomo Cloud. There is a Matomo WP Plugin connecting the Matomo cloud with WP: https://matomo.org/faq/wordpress/why-are-there-two-different-matomo-for-wordpress-plugins-what-is-the-difference-to-wp-matomo-integration-plugin/

@till_mementor Any reason why you are using a 3rd party plugin instead? (If so, which one are you using).

Thank you also for the link to the Strato issues; I found further links that can be related:

Error 500 internal servor Wordpress 6.2

Since updating to the latest version of WordPress on my site, activating Matomo creates an “error 500 internal server” which is not related to a conflict with other plugins since the problem persists when I use it active alone. My PHP version is 8.0.28. How to solve the problem?

(As a new user, I can only add 2 links, please search for “php-8-0-not-ready/49372”)

IONOS recently upgraded to WP 6.2 and PHP 8, so maybe it’s not a IONOS issue but rather an incompatibility with the current version of those two products.

Any updates / additional information will be highly appreciated.

With best wishes,
Alexander

Thank you for the hint. I did as suggested:

Matomo WP Plugin crashes WP hosted by IONOS (Internal Server error)

[till_mementor (Till Mattausch)]

Hi Alexander,

i use this Plugin: https://de.wordpress.org/plugins/wp-piwik/ because all the others I tried lead to the same error.

[hono (Honolulu)]

I’m also using WordPress with Ionos and tried to install the WP plugin, as the thread mentions already, I received a 500 Internal Server Error and can’t allow myself to shut down the whole site for this.
So after trying out what they say in the GitHub threads and nothing was working, I decided to try to install it on-premise on my web server.

I thought this way it’d work, I get to the first installation page, then the system checks where everything’s ok, and finally the database connection page.
I fill out the form and click next. It loads for a while and I get the 500 error again

Here’s the system check:

Dear All,
Today I returned to the Matomo WP Plugin and IONOS is still my hoster. Installing and activating the plugin today (about 1 year later) did not trigger the internal error message anymore.

However, my WP dashboard shows this warning message that can also be found in the Matomo Diagnostics section: There are some errors in the Matomo Diagnostics System report that may prevent the plugin for working normally.

How can I resolve any issues triggering it? Please find a copy of the system report below.

PS: IONOS notified me that they will soon upgrade me to WP 6.5.4., as I use a managed WP hosting, just in case.

JFYI - I have updated the GitHub report as well.

With best wishes,
Alexander

(The detected PHP CLI version does not match the PHP web version. To avoid archiving errors, enable archiving via HTTP requests, or manually set the path to your PHP CLI executable to the one for PHP version 7.4.33.)

• MySQLi support: missing (Your PHP cli does not load the MySQLi extension. You might have archiving problems in Matomo but also others problems in your WordPress cron tasks. You should enable this extension)

PS: It seems that the issues are covered in this KB article that summarizes the discussions: https://matomo.org/faq/how-to-solve-the-error-message-your-php-cli-version-is-not-compatible-with-the-matomo-requirements/

I am contacting IONOS to learn about the exact path and will keep you posted about the results.

Update: After manually setting the path to the correct CLI binaries, this part in the system report looks good:

PHP CLI Version | 8.2.20 |
MySQLi support | ok

JFYI - The IONOS support was helpful and confirmed that “/usr/bin/php” points to an old PHP version and they plan to change this in the future. The setting for PHP 8.2 is

php_binary_path=“/usr/bin/php8.2-cli”
