We’ve had a few isolated reports of a jQuery conflict in the current version of the plugin. After further investigation, we’ve issued a patch for those situations in our next release. * We’re slated for a slow rollout over the next week or so. Once that happens, please try a fresh uninstall/install of the plugin and see if that fixes your problem. I’ll be happy to update the thread once things are released. * Thanks! * Plugin Support [khungate](https://wordpress.org/support/users/khungate/) * (@khungate) * [4 years, 5 months ago](https://wordpress.org/support/topic/cant-connect-module/#post-15412473) * Hi [@attrexx](https://wordpress.org/support/users/attrexx/), I wanted to let you know that v2.6 of the plugin has been released. Let us know if you still run into any issues, hopefully everything is resolved now with the new update. * Thread Starter [attrexx](https://wordpress.org/support/users/attrexx/) * (@attrexx) * [4 years, 5 months ago](https://wordpress.org/support/topic/cant-connect-module/#post-15440447) * I have v 2.6.1 and issue is still present. All modules up to date. * Plugin Support [khungate](https://wordpress.org/support/users/khungate/) * (@khungate) * [4 years, 4 months ago](https://wordpress.org/support/topic/cant-connect-module/#post-15530014) * My apologies [@attrexx](https://wordpress.org/support/users/attrexx/), I’m not sure how we missed your last response. Are you still having trouble accessing the plugin’s set up sequence? We did push another version of the plugin since your last message, but if you’re still having issues it sounds like a case of your server being blocked. We can provide specifics on basic troubleshooting if so. * Plugin Support [khungate](https://wordpress.org/support/users/khungate/) * (@khungate) * [4 years, 4 months ago](https://wordpress.org/support/topic/cant-connect-module/#post-15579657) * Hi [@attrexx](https://wordpress.org/support/users/attrexx/), we’re going to close out this ticket for now since it’s been a few weeks since we’ve been in touch. * Please let us know if you still need any help and we’ll be glad to reopen and troubleshoot further.
