Fatal error on WordPress 5.6.2

I have the same error in this multisite web https://aguadecoco.org/

PHP Fatal error:  Cannot redeclare Matrix\adjoint() (previously declared in /home/agua/public_html/aguadecoco.org/wp-content/plugins/visualizer/vendor/markbaker/matrix/classes/src/Functions/adjoint.php:20) in /home/agua/public_html/aguadecoco.org/wp-content/plugins/gf-entries-in-excel/vendor/markbaker/matrix/classes/src/functions/adjoint.php on line 20

The plugin is currently not compatible with the vizualizer plugin. A temporary fix is to remove the /wp-content/plugins/gf-entries-in-excel/vendor/markbaker folder from the plugin if you have this issue. The plugin will still work, but both the plugins have the same code, and that is conflicting at the moment. I’m looking for a solution, but the best solution would be for markbaker to fix his depedency ??

Hi,

Thank you very much for your quick response.
If I remove the folder I get the following error:

PHP Fatal error: require(): Failed opening required ‘/home/grandesamigos/www/wp-content/plugins/gf-entries-in-excel/vendor/composer/../markbaker/matrix/classes/src/functions/adjoint.php’ (include_path=’.:/opt/php-7.2/lib/php’) in /home/grandesamigos/www/wp-content/plugins/gf-entries-in-excel/vendor/composer/autoload_real.php on line 69

??

Hmm, in that case you can create the file again, but leave it empty.

Hi @freepresscoop,

I’ve opened up a PR for a code change on the conflicting dependency. This will help others as well.

I’ll try to monkey patch my plugin in the meantime. It’s not ideal, because adding code to fix bugs for specific other plugins is a slippery slope. That’s why I hope the dependency can be updated.

I’ll keep you posted.

I have just released 1.8.9. This has a newer version of the dependency that should match the version over visualizer, fixing this problem for now.

Hi Doeke,

I just update to the new version and activate, and works fine.

Thanks for your help.

Cool. Thanks for letting me know.

hi, fatal error with 1.8.9

Hi @tomykas ,

Thanks for letting me know. Would you be willing to try a different version of the plugin to see if that (permanently) fixed the issue?

Please send me an email at [email protected], I can send you over a the patched plugin for testing.

Hi @doekenorg,
I’ve the same issue, always with 1.8.9 version.

hi @lukestephans,

Thanks for letting us know. We are currently working in a permanent fix. Please also let the other plugin know they have the same problem.

Hope to release a fix very soon. I’ll update this topic when the fix is live.

hi @doekenorg,
Thank you!
Definitely inform the other developer as well.
I am waiting for a fix as my clients need to use your export, a very useful plugin.
