Super handy for WordPress Plugin Conflicts Troubleshooting
This plugin makes finding plugin conflicts super easy and quick. I've used it several times to troubleshoot issues on client sites, and it worked great every time. It’s a huge time-saver, letting you avoid the hassle of deactivating and checking plugins one by one!

Te facilita muchísimo el trabajo
Cuando recibes una web con 80 plugins y de pronto resulta que hay un conflicto entre algunos de ellos, este plugin te facilita la vida de una forma enorme. A la caja de herramientas de cabeza. ¡Gracias!

Worthless.
Installed and activated, and i got a 403 error in NGINX. I was able to resolve the 403, but this led to a new issue, “Error establishing a database connection.” I spoke with a programmer, who said "this is not something we can fix as its the way the plugin is written. The database connection IS working properly, so the plugin is altering the method in some way, which is breaking it." Seems that I'm not the only one with this issue. I sure wish Support would respond with a solution.

Dumped me to a 403 page.
I really wanted this to work but unfortunately it just sent me to an Apache "Forbidden" page. Maybe it has a conflict with Wordfence or Solid Security.
