List articles of a category, blog view, with a photo as intro doesn't show up

I have a Flexicontent 3.0.1rc2a installed in Joomla 3.5.1 in LOCALHOST, as a test-site.
In my ONLINE site i use Flexicontent 3.1.1 installed in Joomla 3.6.5.
The problem is that when i list articles of a category, with blog view, with a photo as intro, i can view it in localhost edition, in the online site it gives me plain text with the name of the photo.
I am trying for day to find a solution looking the parametrs of both menus with no luck at all...
A second problem is that i can't order the articles alphabeticaly, putting first some with a user field.
Please help me if you can, i am out of ideas...
Thanks in advanced,
Makis

Hello

i can view it in localhost edition, in the online site it gives me plain text with the name of the photo.

So image is recognized inside the introtext
but the plain text with name of photo instead of photo,
- means that the image URL is wrong (=it is not found)

So if you right click at the image that is shown as text (image filename),
what is the URL image path that you see ?

Doing right click -> "view page information"

at the "general" tab gives me:
og-image: http://sitename.gr/images/Catalog_2016/image.jpg

at the "multimedia" tab gives me:
http://sitename.gr/components/com_flexicontent/librairies/phpthumb/phpThumb.php?src=/images/Catalog_2016/image.jpg&w=200&h=200&aoe=1&q=95&ar=x

As i noticed now, it doesn't give the name of the image file but it repeats the title of the article, in greek language -the image file is in Latin letters.

I enclose a screenshot

Any suggestions please?

Hello

does this image exist ? (is the path correctly ?)
sitename.gr/images/Catalog_2016/image.jpg

Test with SEF OFF

If you have enable SEF , then also rename htaccess.txt to .htaccess

Then finally send me a PM with super admin access

I tried with SEF turned off, with and without htaccess.txt to .htaccess2 (there was already a .htaccess) with nothing to change. I will send you pm with access hopping you'll kindly help.
Thank U in advanced.
