CertificatesWall profile
This plugin is used to display user's achievements in the profile.
The plugins pulls user's data from CertificatesWall.com and display "Certificates Wall" for the user in his Moodle profile.
If the user has no profile on CertificatesWall.com then nothing is displayed.
The aim of this plugin is to allow the student or the teacher to show own certificates/diplomas/awards/badges in the profile on the Moodle site.
This plugin is "profile field" type. To install it:
1. Uncompress the archive .
2. Copy the folder certificateswall to user/profile/field directory on your moodle installation
3. Open custom field editor (Site administration->Users->Accounts->User profile fields)
4. Choose CertificatesWall in "Create new profile field" dropdown.
5. Configure and save the field.
I'm installing this plugin in our linux (postgres) test servers v.2.3.3+ and 2.4.1+. I'm getting the error message below in both servers. Do you have an idea why the version could be defective or updated?
Error:
Plugin "mod_certificateswall" is defective or outdated, can not continue, sorry.

Thanks
Thanks for your report. This plugin was tested on all versions from 2.0 to 2.4 .
However, i will try to recreate your problem and fix it.
I discovered that I need to install both the Certificate Wall and the CertificateWall profile plugins in order for them to work. Once I installed both I didn't get the error message anymore.
Thanks for your time
This plugin will work in moodle 2.6?
