Plugin fails immediately with critical error

[MxFxM]

DataExport 1.1.5 Matomo 5.1.0 Wordpress 6.5.5

I install the Matomo Plugin via the Matomo Marketplace Plugin (not via downloaded zip, because I cannot upload that but that's a separate issue on my side). Then I activate the plugin. When I go to the Matomo site settings and then DataExport I get this:

Error message: Failed opening required '/var/www/vhosts/inventife.com/httpdocs/wp-content/plugins/matomo/app/plugins/DataExport/vendor/autoload.php' (include_path='/var/www/vhosts/inventife.com/httpdocs/wp-content/plugins/matomo/app/vendor/pear/archive_tar:/var/www/vhosts/inventife.com/httpdocs/wp-content/plugins/matomo/app/vendor/pear/console_getopt:/var/www/vhosts/inventife.com/httpdocs/wp-content/plugins/matomo/app/vendor/pear/pear-core-minimal/src:/var/www/vhosts/inventife.com/httpdocs/wp-content/plugins/matomo/app/vendor/pear/pear_exception:.:/opt/plesk/php/8.2/share/pear') in /var/www/vhosts/inventife.com/httpdocs/wp-content/plugins/DataExport/Controller.php line 11

Hi, thank you for submitting this issue.

This issue seems related to installing the plugin in a Wordpress environment. I haven't tested that, but I can post an updated version in a couple of days to resolve that issue.

A quick fix would be to just remove the autoload feature, it is only used to upload backups to AWS S3 Buckets.

Thank you for the quick reply!

How would I remove the autoload feature?

I added a condition that checks if the file exists, I assume that your hosting doesn't like absolute paths. Which is probably why you get that error. If you try install it again, could you let me know if it works?
