Not loading questions in IE from numbas editor #117

Closed BillFoster closed 11 years ago

BillFoster commented 11 years ago

Freezing on loading.

christianp commented 11 years ago

Can you give a link to one that doesn't work? The ones I've tried work.

BillFoster commented 11 years ago

More often than not, when first going in and loading a question it usually does load, but on subsequent attempts the error appears on the page, Refreshing loads the question. Sometimes on refreshing a warning appears re a script running in the background slowing things up.

Questions are not loading in IE in numbas-editor, but exams are and are running properly as far as I can test

BillFoster commented 11 years ago

Using IE, no questions are loaded in numbas-editor, even after clearing the cache.

christianp commented 11 years ago

Wow! Even the error dialogue crashes, so I can't see what's wrong. That's only in IE8 mode - IE9 works OK. I have absolutely no idea how to fix it. Literally anything could be wrong. I didn't mean to close this bug anyway - I referred to it in a commit message with the wrong set of words.

Looking at http://numbas.mathcentre.ac.uk/test-yourself/chain-rule-practice/ in IE 9 the advice is being displayed under all the headings

Can you check that fix works for you, please? Silly github keeps closing the issue.

BillFoster commented 11 years ago

I can't get that to happen. @anthonyyoud?

BillFoster commented 11 years ago

See attached for two problems - advice included in all headings and also another error which is self explanatory

Oh, I thought you meant that all the headings were "Advice"! I see that you meant that the advice appears no matter which heading you click on.

I don't get the second error - what is it?

This is why it's always a good idea to use more words in sentences.

christianp commented 11 years ago

Weirdly, the error only happens on the servers, not on my local editor.

christianp commented 11 years ago

Right, the advice always appearing error seems to be fixed.

BillFoster commented 11 years ago

Apologies - forgot about your colour-blindness! You will still see that the screen shot reports from the Advice:

Invalid expression f'(x)=h'(x)g'(h(x))

This is accepted by Chrome

It's not accepted by Chrome. It's a difference between the editable view and the non-editable view. The culprit is the use of inverted commas instead of apostrophes for the primes. I'm not sure how it happened - I would blame TinyMCE, but when I made a copy of the question and just pressed space to make it resave, it converted the inverted commas to apostrophes. It might be an artefact of the upload process from when things were in .exam files.

Non-editable view using IE8 on numbas.mathcentre editor gives error on page and does not load the information in the tabs

BillFoster commented 11 years ago

Can this be closed now?
