Could you please tell us which version of Moodle, whether you were installing the activity or

the tinymce plugin, and which folder you were installing into?

Re: Nanogong error

I have moodle 2.00 and installing both the activity module and tiny mce plugin.  I followed the instructions on the nanogong tutorial to the T.  The activity in the mod folder and the tiny mce in the lib/editor/tinymce/tiny_mce/ and I also copied and pasted the code provided in the lib/editor/tinymce/lib.php file as instructed. 

php file attached.

The Nanogong documentation shows they did extensive testing for Moodle versions 2.0.8+ and 2.1.5+ and 2.2.1+ but some folks have been having problems with them anyway.

Personally both the activity and plugin worked as advertised in my Moodle 2.3+ dev site but only the activity worked in my production 2.2.3+ site without making some changes.

To get the plugin to work I had to change the nanogong.php file in the plugin as noted by Nicolas Dunand in the release because it was not finding the other plugin files.

There have been a number of TinyMCE versions - you have my production site is 3.4.9, and my dev site is that might be the cause of the problem although I suspect it might be partially due to the changes in the site config.php file. I had to change mine for my production site to get the Nanogong filter to work.

Anyway, here is a copy of the plugin file I changed. I added line 55 and commented out 56.

Re: Nanogong error

Hi Pam,

I know it's a long shot, but here are my findings.

Whenever you see this error, it means that the DB tables relating to mod_nanogong are out of date. This typically means that you have tables from mod_nanogong for Moodle 1.9.

The solution is simple: just remove mod_nanogong from admin interface, and install it again. There is no code change required. After re-installation, DB tables working with mod_nanogong for Moodle 2+ will be created, and mod_nanogong will work.

Note that performing this will remove any data related to mod_nanogong for Moodle 1.9. AFAIK, there is officially no way to migrate mod_nanogong data from M1.9 to M2.
