Thumbnails images missing

Ah!! We do progress!! Thanks!
In the Universal content module, I modified the parameter in the tab:
Gestion du contenu via paramètres 
Under the section:
Image
I was on :
Yes, resize
with size parameters

I changed it ot:
Medium size thumbnail

And it now works!

So I guess something somewhere was not liking the parameters like:
https:/&w=110&h=110&aoe=1&q=95&zc=1&f=jpg

I still have a problem with the image of the category displayed at the top of this carousel, you can have a look at the bottom of this page for example :

www.rouchenergies.fr/photovoltaique/en-autoconsommation.html

As you can see, the image of the category is not displaying ont the front-end, although it displays perfectly on the back-end : 
 

For a category, where can I find the parameter to change the way this thumbnail is resized? Can't see it.

PS: I noticed that the icons for Save etc are missing when I'm working on a Flexicontent module (only on Flexicontent module. I don't have this problem with items or with modules not from Flexicontent) 

Any idea about this?

what is your flexicontent and joomla version to be more clear ?
if its a joomla 5 or 6 try this update
github.com/FLEXIcontent/flexicontent-cck...efs/heads/master.zip
=> that add many bug fix and complete joomla 6 compatibility but you need to check your module and template configuration we do some update on display
(maybe on staging site at first)

Hello

I'm working on a live site, so I can't risk a beta version. But the problem isn't that serious, so I'll wait for a stable version to be released.

I would have liked to contribute with a test site to help you move towards a Joomla 6 compatible update, but I am not a webmaster, and managing our website is already a job in addition to my own (which is more than full-time).

Thank you.

thanks for any return

Hello,

OK. But, for now, I'm still looking for the place where I can do on the Category the same thing I did with the Universal content module = change the parameter in the tab:
Gestion du contenu via paramètres 
Under the section:
Image
I was on :
Yes, resize
with size parameters

I changed it ot:
Medium size thumbnail

This worked for the Universal content module, so I guess something somewhere was not liking the parameters like:
&w=110&h=110&aoe=1&q=95&zc=1&f=jpg

I still have a problem with the image of the category displayed at the top of this carousel, as you can see here :

 

Here, the link to the thumbnail looks like :
/components/com_flexicontent/librairies/phpthumb/phpThumb.php?src=//images/banners/images-diaporama/1280x800-pour-microdata/pompe-a-chaleur-blog-actualite-1280x800-min.jpg&w=127&h=79&aoe=1&q=95&f=jpg

➡️ Where can I find this resize parameter on the Category when it is displayed above the carousel of the Universal content? (because if I display the category "normally", in a category blog, the image is displayed normally, without any parameters at the end of the src link : Flexicontent only adds theose parameters inside the Universal content module)

for now no idea => you need to find why phpthumb doesn't works and all be solved
flexicontent works on many site without limitation. Phpthumb can be broken or blocked only by avaibility of php module (gd or imagmagik)
its important to check this
