Hi @thunt4jr,

It seems that a description is missing, and that's why it could not be listed in the "following errors".
Here's the PR about that issue in https://github.com/PrestaShop/PrestaShop/pull/9407.
If you're confident in modifying the core files manually, you can apply the changes to show the test in failure.

Best regards, Khouloud

[thunt4jr]

It is also an issue with products that have over 10,000 wordings. New products and old products is the same issue.

[thunt4jr]

I found the problem, it is posting in the database but not display on the backend. it will come up on the front end. So the description is not the problem. This is still an issue and looking for the solution.

[khouloudbelguith]

Hi @thunt4jr,

So your issue is that products are saving in the Database, but not in the Back-end?

Best regards, Khouloud

[dave-lw]

i have a site with same problem too... but i dont believe it updates the db at all.
You can get me in hangouts Khouloud

[dave-lw]

thunt4j make a test php file

<?php echo iconv_strlen("Test iconv_strlen here", "UTF8"); ?>

if that error 500's either iconv.so exension in /etc/php/php.ini is commented out/disabled for some reason, or in my case there is a problem with it because it is active as shown by phpinfo...

[thunt4jr]

It turned out to be PHP extension not installed on the server side. Iconv and 4 other extensions not installed. The server went from easy apache 3 to 4 without updating or finishing the installation. It work fine on my server until I transfer it to their server.

[dave-lw]

awesome, glad it is solved for you!

[marionf]

Maybe we can add it as a requirement during install process ? @eternoendless

[thunt4jr]

@marionf the problem with that was I had it on my development server before I transferred it to their server. It does show the extension that is required to be install when you install a fresh copy of Prestashop onto the server. What it doesn't show is the requirements when you transfer it. Maybe add in the Server information section in Advancement Parameters > Information what is required?

@khouloudbelguith

Could you try with 1.7.6.x branch and tell us if you have any warning during installation if inconv extension isn't enabled ?

[khouloudbelguith]

Hi @marionf,

Yes, we have warnings during the installation if iconv extension is not enabled.

I close the issue.
Thanks!

[marionf]

Great ! Thank you @khouloudbelguith :)
