Prestashop Native Link Widget 500 Error

[Jonss]

I'm new to Prestashop (1.7.5.1)  and I'm having a serious issue with Prestashop native module (Link Widget)

I don't know why but I keep getting this "500 Internal Server Error" every time I try to open the (Design --> Link Widget) :

https://company.com/admin-97521/index.php/modules/link-widget/list?_token=-37sb79hXhJmHBYvsqNqXoeWZhVZRjOj3Vxk1x2ndRM

Oops! An Error Occurred
The server returned a "500 Internal Server Error".
Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused.

I have tried to - RESET, DELETE and REINSTALL the module yet nothing is working, I have no clue what I should do to make it work.

Is this module somehow dependent on some other file or module.

How do I fix this please help me

Please tell me how to fix these.

Bonjour,

Same error in one of my shop, don't find the way to fix the problem.

Will be interested is somebody know how to fix it.

Thanks

[gbouille]

Hi,

I have the same issue with "Prestashop 1.7.5.1" and all modules updated...

[Jonss]

I managed to fix the issue by deleting the [cache folder] the Root install folder.

I don't know if this is the best solution, but you can test if this will work for you.

Backup before you delete.

Thanks for your post Jonss, you delete the /cache folder in the root folder or in the /var/cache ?

Thanks & regards

[Jonss]

I deleted the cache folder in the (Root Folder)

In other words the cache folder inside the (public_html folder) if you are using C-Panel.

Ok thanks. This no solve the solution for me.

[Jonss]

After deleting the cache folder, you should also clear your browser history.

Another thing you could try is open cmd as admin and type

ipconfig /release enter

ipconfig /flushdns enter

ipconfig /renew enter

If this does not work then sorry man, you are left with the only option of re-installing prestashop from scratch !

[JBW]

cache folder on root level is depreceated on 1.7.5 - the new location is /var/cache - wondering how the deleting could have solved your issue. @thomasharko try with renaming /var/cache to /var/cache_old

Thanks JBW, renaming /var/cache to /var/cache_old unfortunately don't solve the problem.

Try to replace your ps_linklist by this one

ps_linklist.zip

Thanks Janet but still no success.

Remove the module, remove cache, install the new one but still the same error.

Class "PrestaShop\Module\LinkList\Controller\Admin\Improve\Design\LinkBlockController" does not exist.

[Janett]

I think your composer autoload is broken.

Did you know execute CLI commands ?

Because you should execute

composer dump-autoload —no-dev

On the root folder of your PrestaShop

Then do the same command in /modules/ps_linklist directory

Bonjour Jannet,

Thanks

I execute the command, find below the results

On root folder of the shop : Composer could not find a composer.json file in /var/www/vhosts/domaine.fr/httpdocs/domaine.fr
To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ "Getting Started" section

On ps_linklist module folder : Generated autoload files containing 1 classes

For the root folder command, should I start again with an empty composer.json or copy the composer.lock to a composer.json file ?

Thanks again

Have a nice day and a nice week-end

Thomas

You can retrieve from here : https://github.com/PrestaShop/PrestaShop/blob/1.7.5.x/composer.json

Thanks Janett.

Ok I execute the command on both and empty var/cache but no success. Still the same error on the module ps_linklist page.

Result of the command on the root folder : Deprecation warning: Your package name PrestaShop/PrestaShop is invalid, it should not contain uppercase characters. We suggest using presta-shop/presta-shop instead. Make sure you fix this as Composer 2.0 will error.
Deprecation warning: require.beberlei/DoctrineExtensions is invalid, it should not contain uppercase characters. Please use beberlei/doctrineextensions instead. Make sure you fix this as Composer 2.0 will error.
Generated autoload files containing 110 classes

Here there are a problem, there more than 1 class in /modules/ps_linklist/src

Composer should add it in autoload 🤔

[El Cuartito diseño]

1-Uninstall the module
2- Clears cahe smarty
3- Delete modules / ps_linklist in the server
4 - Reinstall the module version v2.1.6
it works correctly
NO UPDATE THIS MODULE againg

[thomasharko]

Bonjour,

Going back to 2.1.6 works.

Thanks

[FaheemTariq]

Dear thomasharko, can you please tell me how did you do that? i mean how did you downgrade to 2.1.6?

[thomasharko]

Bonjour FaheemTariq,

You need to uninstall and delete the actual module

Then remove all files and folders in /var/cache/

And install the module downlodable to the link https://github.com/PrestaShop/PrestaShop/blob/1.7.5.x/composer.json

Have a nice day

Best regards

Thomas

[FaheemTariq]

Thank you so much Thomas, it worked. 🤗

Hey guys,

Thanks for all the effort and help you are offering to the community. Forgive me I am newbie so I need some guidance.

I have this issue with the latest version of Prestashop 1.7.6.2. Everything was working fine but then I installed this theme and I got the same internal 500 error as described above. I have renamed the ps_linklist folder in the modules section and most of the issues are sorted sorted except the link widget itself. I can not access it cause obviously the module is not present now so I need to downgrade it.

I am not exactly sure how to perform the following action : 

" install the module downlodable to the link https://github.com/PrestaShop/PrestaShop/blob/1.7.5.x/composer.json"

 

I would really appreciate if someone can refer me a video link or an article or make some basic bullet points on how to downgrade link widget.

 

Thanks in advance.

Regards

Muchas gracias Thomas, funcionó. 🤗

Hola, podrías indicarme como conseguiste descargar el modulo en su versión 2.1.6  . Gracias.

I have the same problem,

("Oops! An Error Occurred

The server returned a "500 Internal Server Error".

Something is broken. Please let us know what you were doing when this error occurred. We will fix it as soon as possible. Sorry for any inconvenience caused."),

followed all the instructions and the problem persists. If I can't fix this I might as well de-install the whole thing, as the shop is useless if you can't configure that module.
