Hello everyone!
Well I have an issue with Guide GUI's. I will run a GUI based program and it will display a gray box the correct size, but it has nothing in it, all the buttons or displays or plots do not show up at all. It remains an empty gray box...
I have tried a few different GUI's and even made one with all of them having the same result. I run MATLAB on a linux, I know I have had the GUI's working in the past, but now they don't. I'm not sure what changed, it could of been in an automatic update, I don't know.
This is a post found that looked similar, but it did not seem to really answer how to fix the issue:
It happens to all GUI's so I did not think I needed to add code. I did try looking it up too, I found others with the same issue (it looks like it could be some type of Java issue, but I'm not sure), but did not really find a way to fix the issue.
Any help will be very appreciated!!!
Please if you know how to fix it, let me know!

Based on the link you gave, that, Java version 7, is the problem.
If possible try to downgrade the java, and check whether the probel persist.

Hi. This is my prlbem:
When I connect java to new java (version 6) and run it I have this error :
Fatal Error on startup: Cannot locate or initialize class com/mathworks/jmi/OpaqueJavaInterface. java.lang.UnsupportedClassVersionError: com/mathworks/jmi/OpaqueJavaInterface : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
I'm downgrading java 1.7 of Matlab R2014a to 1.6
Thanks.
