Hi, GraphicMemory.
This is the first time this problem has come up with the plugin, so would you be able to share which version of WordPress you have installed, as well as which other plugins are installed?
Otherwise, I would try temporarily deactivating all other plugins and then see if you can activate it, as another plugin could be causing this. If that doesn’t work, please try enabling one of the WordPress themes, such as Twenty Seventeen, while all other plugins are deactivated still, and then see if you can activate it. This will either eliminate or confirm that another plugin or theme is causing the problem.
Thanks,
John
I was receiving the same error message running 4.8.3. As for plugins, I have about 29 activated so deactivating them one by one would be pretty difficult.
Hi, thebark. Would you be willing to provide a list of plugins that you have installed and activated? I can then test those plugins on my own server. The biggest problem I’m running into is that I can’t, yet, replicate the issue so I’m not able to fix the problem.
GraphicMemory and thebark, are you able to install and activate any other plugins?
The likely culprit is another plugin and reinstalling all of them should fix the problem.
