Why's getFileInfoForToolstrip missing after update to R2018a

Since updating to MAtlab R2018a, I have been getting the error: Undefined function or variable 'matlab.unittest.internal.ui.toolstrip.getFileInfoForToolstrip', periodically in my command window. Specifically happens every time that I save a file in the editor.

I get the same error since I've installed R2018a and open matlab.

I also get the same error

I also saw that if i closed all files, cleared workspace and restarted Matlab 2018a, I got multiple errors regarding missing files/folders. Browsing around, I saw those folders did exist in my 2017a tree but have been deprecated from my 2018a tree. (example is: C:\Program Files\MATLAB\R2017a\toolbox\matlab\addons\fallbackmanager). I added one of these directories in the 2017a tree to my path, and restarted 2018a. No errors on restart! Then I removed the 2017a folder from my path and again restarted 2018a. To my surprise, still no error at startup.

However... I still see the same error: Undefined function or variable 'matlab.unittest.internal.ui.toolstrip.getFileInfoForToolstrip' each time I save a file I've edited.

For performance purposes, MATLAB caches a list of files on the MATLAB search path (including toolbox files), and this cache can persist even after closing MATLAB (but not after restarting your machin). It seems that this cache is getting into a bad state on your machine.

Try the following commands:

restoredefaultpath
rehash toolboxcache
savepath

If the above fails to resolve the issue, try restarting your system.

Thanks. The suggested commands did indeed fix the problem. I did not need to restart.

[Shunyuan Zhang]

Thank you! The commands worked, without restarting the system.

I am sorry, but neither option worked for me. I am running MatLab 2018a (9.4.0.857798) on a MacBook Pro (15inch, retina, late 2013), and I am getting the following three lines upon start-up:

Undefined function or variable 'matlab.unittest.internal.ui.toolstrip.getFileInfoForToolstrip'. Undefined function or variable 'mls.internal.FevalService.init'. Undefined function or variable 'connector.internal.lifecycle.callConnectorStarted'.

As described in the previous postings, the first of the three shows up each time I try to save a file.

Is there another, deeper way of getting this fixed?

Thanks

[Antoni]

Thanks! I had the same problem and the suggested commands fixed the problem.

[Edward Barile]

Excellent! Thanks - it worked

[ANTHONY REID]

This solution worked for me too.

[Taewook Kang]

Thanks a lot. It worked for me too.

In my case, I changed the version 2018a -> 2019b.

[Henan Yu]

Sorry, not working for mine. Still getting these errors and I cannot do anything with matlab, even I re-installed twice.

Unrecognized function or variable 'rmiml.visibleInToolstrip'.

Unrecognized function or variable 'rmiml.visibleInToolstrip'.

Please help me with this

Thank you

Thank you so much! My MATLAB was not working as well and this really helped! Thank you again :)

In addition to Sonam Gupta's comments, be sure to check the Matlab startup folder.

(On windows, the default is %userprofile%\documents\MATLAB\ )

If there is a pathdef.m file there, Matlab will load this on startup. See if removing or renaming this file solves your issue.

I get the same three errors, but restoring the path or reinstall Matlab does not work out. Any suggestions?
