Hello,

Problems fixed.

It come from native plugin social media share.

I desactived it.

All is nice now.

Thank you.

Can you please elaborate what was the error with that plugin?

1. Arxive maked automatic Oxwall Installation.

2. All is correct.

3. I configured social media share.

4. I can see it in Home page and sharing work great.

5. I begin to create one post in blog section.

6. When i click in the post, the post is appearing no properly but at this time home page and others pages appear properly.

7. I create a topic in section forum. It seems like just above in number 6.

8. Now when i see home page, social media share is disappeared but here in customized mode.

9. At this time, the most pages doesnt appear properly.

10. I think the plug-in social media share make problem, so i desactivated it.

11. Now all is good.

12. After your message above, i reactivate plug-in.

13. Home page doesnt appear properly and now i cant navigate in my website with a error.

14. I desactivate again and all is correct.

Nico, can you please activate it again, and send me the screenshots of what you're referring to as an improper appearance of pages and post?

I will ! after my job. 

Otherwise, please refer once again to attachment screenshot in my above message and look we cant see header, footer etc.

Look website : http://www.oxwall-fr.org

And compare design of attachment file and website.

Thank you very much.

Ross,

Please look at the attachment to look what the problem when i activate media social share plugin.

Ross,

All is Ok now!

Social media sharing is good to use now since i update Core + plug-in (Oxwall 1.7)

Thank you.

Alright, then. Too bad we could not check it for 1.6 as this is a native plugin and the issue should have been solved. Anyway, I'm going to mark this post as Solved then. 

Sometimes i have this kind of problem. When i know the plugin make this mistake i uninstall it and reinstall it and all is done.

I think the automatical update are not always stable and may corrupt somes files.
