I have two joomla installations localhost and webserver. Both have same Joomla version and different PHP versions. But both PHP versions are supported by joomla.
I have installed jBackend3.5.0_J3 on both. But it works on remote server and not on local machine.

On localmachine, the backend does not work and it works on remote server.
When I check jbackend plugins in jbackend component, they are disabled but enabled in Joomla extension manager. When I click on the plugins in joomla component, I get error. Please see attached screenshots.

Local machine - not working


Local machine - not working



Remote server - working




What can be reason for the problem?

Hello Luigi,
Thanks for the reply.

I am sorry for unclear post.

It does not work means
1. It does not show that the jbackend modules/plugins are not enabled. You may see small red crosses in image 1.
2. It does not return any information when I put http://localhost/joomla/index.php/rest/get/content/articles/1 in my address bar. It opens webpage of the article. I expect JSON of article 1 or some error.

Regards

Hello Luigi,
Thanks for the reply.
I tried to enable the plugins by clicking on them, but nothing happens(they show red cross refer picture 1). But when I check same plugins in joomla plugin manager, they are enabled.(check picture 2)

Regards

Today I updated the remote server website to 3.7.5.
It asks me to upgrade Jbackend.

Name Location Type Installed Available Folder Install Type URL Details
jBackend 3.5.0 Site Package 3.2.0 3.5.0 N/A Update www.selfget.com/updates/jbackend.xml www.selfget.com

Note that name has 3.5.0, but installed version info shows 3.2.0.
