worst plugin ever, do not even try it

Hi nasional, can you show us a page with the issue?

thank you very, very much for your answer I am desperate!!!

here is the link to my website, I decided to delete all the images I had so I can upload them again and see if that would solve my problem.
I have already delete the REGENERATE-THUMBNAIL plugin, I do not want to use it anymore or having it inside my website.

the link tom my shop is:
https://nasionalsb.org/tienda/shop

That page doesn’t appear to have images, do you have an example of the pixelated issue?

I deleted all the images to upload them again and see if that would solve my problem. That is the reason why at this time the site has no images.
But no.. Though I have the original images inside an external hardrive, I have upload a few already and still have that pixelated effect I want to get rid of.
The problem is on the listing page of my woocommerce website. There is no second chance for a first impression. If a customer gets into the store and see those awful images probably no purchase will be made.
here is an example of how it display the images:

<img src=’https://s9.postimg.org/5pgog43cb/Captura_de_pantalla_2015_11_02_a_las_16_02_47.jpg&#8217; border=’0′ alt=”Captura de pantalla 2015 11 02 a las 16 02 47″ />

I see. There’s a better chance of us being able to explore the issue if we can see a live working example of it.

thanks again for your help.
now you can see a live working example as I am uploading the original images I have inside an external drive, but the pixelated issue still persist.

Some images are lost, but you will see live examples of my problem.

If you’re not using a Child Theme, and if the theme doesn’t have a designated section of the dashboard for CSS modifications then do the following:

1. Install this Custom CSS Manager plugin https://www.ads-software.com/plugins/custom-css-manager-plugin
2. use its “CSS Code” section of the dashboard to hold your CSS modifications:
3. (put this code in)

   html .woocommerce ul.products li.product a img,
   html .woocommerce-page ul.products li.product a img {
       width: auto !important;
   }

4. Save

Alternatively use your Child Theme style.css file to hold your CSS modifications

thank you very much.
the thing is after using that evil REGENERATE-THUMBNAIL plugin whenever I try to install a plugin I have this message:

Unable to create directory uploads/2015/11. Is its parent directory writable by the server?

the regenerate-plugin residues are driving me insane.

Could you contact your hosting providers and ask them to make the ‘/wp-content/uploads/’ directory have the ‘755’ permissions? If they do that, could you ask them to check that your ‘/wp-content/uploads/2015/11/’ folder has ‘755’ to test it?

the permissions are set to 755 and in fact I am using a Child theme.

Can you install a plugin manually for now? https://codex.www.ads-software.com/Managing_Plugins#Manual_Plugin_Installation

Oh sorry you have a Child Theme, so you need only place that CSS in your style.css file and not use a Custom CSS plugin.

thank you, very, very, very much.
It works.
you are a genius. I really appreciate all your time, support and patience.

Thank you for real, you save my life.

You are welcome and I’m very sorry that you had an upsetting experience.
