quotient I think that this used to work, and that this general sequence of steps is sufficient to produce the problem:

1. Do a problem (press easy, hard, etc.)
2. Now that you've been taken to a new problem, press back in the browser so you're on the original problem
3. Complete it again (press easy, hard, etc.)

Expected: You go on to the second problem again.
Result: You come back to the home page (https://internetgoschool.com/index.vhtml) with large red text at the top saying "Error: could not update problem state: Column 'state' cannot be null".

xcombelle To my knowledge you have to have additional condition such as being on having a long pause on your study, such as keeping the browser open between two days of training

ndbgo This has been broken for a while, and I think Darrell has it on the list of things to fix. It only happens if you change a problem from "learned" to "learning" (that is, forgotten) with the back button. If you only change the difficulty level, things work as expected.

quotient I thought I was just changing the difficulty level both times that I tried it yesterday, but I may be mistaken.

quotient I tried it a couple more times today, just updating the difficulty level, and that worked okay, so I think I recalled my earlier behavior incorrectly and ndbgo is correct.

claude This one should now be fixed.
