Validation state: Validation completed with errors, but no error shown

Dear experienced market leader

It shows: Validation state: Validation completed with errors. But no error shown. 

Do you know anything about this case? 

Thank you in advance and best regards

We had a post exactly the same as this maybe a few days ago.

Seems just another glitch in the endless glitches with validating a product.

Thank you so much for your continuing support, Keith!

Just received the same blank completed with errors response. The validation process is unusually slow as well. Looks like the glitch is back.

Edit: Tried again. The system confirmed "internal error."

Edit: Glitch has been fixed. The same ex5 file successfully validated within several minutes.
