Material Theme UI Plugin is automatically disabled after updating to IntelliJ 2018.1 release for several IDEs (Idea, Webstorm, PyCharm).
If you search for the plugin in the repositories, it shows "installed" and enabled (check mark), but it is nowhere to be found on the "Tools" dropdown, where it usually appears.
The only way is to manually uninstall the plugin, restart the IDE, install the plugin again and restart IDE again.
Even then, the current plugin version (2.5) says "this has been pushed by mistake, there might be bugs".
Plugin should persist across IDE updates.
Plugin is disabled. Needs a full reinstall to activate.
Please go to IntelliJ IDEA -> About IntelliJ IDEA (Mac) or Help -> About IntelliJ IDEA (Windows) and copy the infos
to the clipboard and paste it here.
It should contain:
Are you sure you鈥檙e not using the now obsolete Eap?
You wrote that you have the 1.6 installed while the latest version should be the 2.1.5
I have version 2018.1 and the theme doesn't install. I have version 1.6.1 of Material Theme UI installed but it is disabled. It doesn't show EAP on the name, just the Material Theme UI
I had had EAP a long time ago and switched to the non EAP... however, I just now uninstalled, rebooted, and reinstalled the theme... now version 2.xxx is installing... weird.

Yes, I've always been using the main IDEs. I've only had RubyMine EAP, but I never used it.
You wrote that you have the 1.6 installed while the latest version should be the 2.1.5
Prior to the 2018.1 release, I had the 2017.3.5 version. In that whenever there was a pop-up for plugin updates, I did update. And the maximum the Material Theme UI plugin was updated to, through this process, is the 1.6 version.
So unless upgrading to the 2.1.5 version required a manual reinstall of the plugin, I don't think I missed anything.
I'm experiencing the same behavior in RubyMine 2018.1. After uninstalling and restarting, I also see the warning message about the 2.1.5 release when attempting to re-install:

Installing the 2.1.5 release restores everything back to my previous Material Theme settings.
This warning states that I pushed the version ahead of its time and may contain bugs - which it does. Still it鈥檚 very stable and you can use it in your day to day work.
There is an upcoming version that you can find in the plugin page inside the eap tab.
I'm using 2018.1.1 (not EAP) and the plugin appears to be disabled and missing as well. The plugin version shows 1.6.1.
When I look in the plugins list it's there and checked, but it is red for some reason.
Just had the same issue. Version seemed 'stuck' on 1.6, only updated once I uninstalled the plugin and restarted the IDE
Closing for the sake of closing weird non reproducible issues:
The last version for EAPs is 2.1.5.3. A 2.1.6 is in preparation but that will work only for 2018.1 and EAPs.
2017.3 and AS 3.1 are obsolete and stayed at 1.6
Really?
Closing for the sake of closing weird non reproducible issues:
Even with so many people confirming it's the same issue and on the regular (non-EAP) versions, it's "weird" and "non-reproducible"?
What do you suggest to do? I don't know why people would need to uninstall the plugin and install it again in order to get the last update.
So leave it open? Or better yet, attach a label like "Help Wanted" and "Bug" so that if other open-source contributors are interested can work on it and identify a fix?
Clearly, when people are required to uninstall and reinstall to get the disabled plugin working again after an update, something is wrong?
I can leave it open so people would not open an issue again, yes. But still it is out of the scope of the plugin. Why would the plugin cease to update itself? It's something wrong with the plugin system, not the plugin as well.
Anyway perhaps the next update will fix this
I had the same issue - upgraded Rider to 2018.1 and the plugin showed being incompatible with this version.
The plugin was stuck on version 1.6.1 and didn't show any updates were available.
I had to 'browse repositories' from the plugins section of settings to see an update was available. Updated and everything worked as expected (v 2.1.7.1)
Closing. Thanks for the help
