Hi Gordon,
I just upgraded the plugins, HotPot (2016042088) and TaskChain (2016042008) via the notification page. My Taskchains now lead to a 404 Page error. I can add a new TaskChain but it still shows the same error. I am using Moodle 2.9.3+ (Build: 20151119).
Any ideas?
Thanks,
Jeff
When clicking on some TaskChains get:

The page you've requested can not be displayed. It appears you've missed your intended destination, either through a bad or outdated link, or a typo in the page you were hoping to reach
That suggests you have no file at:
Please check if that file exists and let me know.

Something is gone awry with the permissions or server settings on the "shs/moodle2" website
For example, this URL shows a list of quizzes in your "APC_TRI3-MJ" course:
Therefore the following URLs should show the TaskChains and HotPots respectively, but instead the browser gets whisked off to what looks like a WordPress site:
Perhaps the permissions or ownership on the "mod/hotpot" and "mod/taskchain" folders are not correct. Please make sure they are the same as the other sub-folders within the "mod" folder.
I suspect that the permissions are wrong on HotPot and TaskChain folders, which means your webserver (Apache?) cannot access the PHP files and thinks they are not there. Additionally, you have set up your server so that "404" errors are redirected to the "shs" WordPress site .... does something like that sound plausible?

Gordon
The TaskChain were working just before the upgrade.
The folders were set at 755 which means group and world did not have write access. Just change to 777 which appears to changed the subfolder to 777 too.
I get the same redirect. I have been testing the SGChem1 course.
Later,
Jeff
Do the webserver logs reveal any more information about what might be happening?
Under Stats and Logs there is an Error Log and it is empty.
If you use a PHP accelerator (e.g. PHP-FPM), you could try clearing its cache.
Another idea ... all non-existant files lead to that 404 page. e.g.:
So if I were you, I would try find out where 404 redirection is being handled, disable it, set Moodle debugging to DEVELOPER, try accessing the TaskChain page again and then see what error message you get in your browser.
What happens of you create a completely new php file within the TaskChain folder, for example:
And in that file you put simply the the following ...
Does that also cause the 404 error when you access the following URL?
What about if you move that file to "mod/quiz/aaa.php" and then try the following URL?In the interim, I tried the nuclear option. I uninstalled both the HotPot and Taskchain modules. Deleted the folders and re-stalled latest versions. Both the HotPot and TaskChain activities work now. However, if I try to set conditions for the tasks. the popup windows for setting the condition is blank.
Such as:
If I re-extract the TaskChain so that it over-writes the folder and files, the 404s happen again.
If I uninstall again and re-install, they work again but again task conditions cannot be set.
I enabled Moodle Debugging and tried adding a condition to a TaskChain task. That gave the following error
Fatal error: Call to undefined method
MoodleQuickForm_heading::MoodleQuickForm_heading()
in /shs/moodle2/lib/pear/HTML/QuickForm/element.php
on line 363
This gives me somewhere to start looking.
I have made small change to TaskChain to fix the error in the TaskChain conditions window in Moodle <= 2.9. Please could you update your TaskChain module at the next convenient opportunity.
I don't think this is the end of the problem, but it will allow us to move forward.
Hi Gordon,
TaskChain update accomplished. Can set conditions now.
What next?
Thanks,
Jeff
Hi Jeff,
it seems that TaskChain is working is expected now then, except that ... all the TaskChains have disappeared
When you said you "uninstalled both the HotPot and Taskchain module", did you do that by clicking the "Uninstall" link on the plugins overview page?
Gordon
Jeff,
glad to hear the 404 errors are fixed.
You said:
Yes I did uninstall on the plugins overview page. It seemed as though that was the only way I could get the TaskChains and HotPots to work again without the 404 error. It is not a big deal. It is very easy to recreate a TaskChain. I have all my HotPots foldered together according to topic. It is a matter of zipping them and resetting the conditions.
I have split off the discussion about "Free access after specified grade" into another thread:

Gordon
