Ticket #26543 - ERROR ON HOME

Hola,

Estamos detectando un problema bastante extraño con la
combinación/minificación de CSS en Alysum y hemos conseguido acotarlo
bastante.

De forma aleatoria (normalmente al cabo de unas horas o al día
siguiente), la home comienza a verse mal. Los dos síntomas principales
son:

El widget Lookbook pierde completamente su maquetación y los productos
aparecen amontonados.
Los widgets de PK Links / categorías muestran los puntos (list-style:
disc), como si no se estuvieran cargando sus estilos específicos.

Si regenero el CSS desde Creative Elements y después limpio la caché
de Alysum y de PrestaShop, todo vuelve a verse correctamente. Sin
embargo, pasado un tiempo vuelve a ocurrir sin haber realizado
cambios.

He comparado los CSS generados y he encontrado una diferencia importante:

El CSS correcto pesa aproximadamente 263 KB.
El CSS incorrecto pesa aproximadamente 256 KB.

En el CSS que falla faltan varios bloques completos, entre ellos:

Los estilos específicos del elemento .elementor-3010000
.elementor-element-164639b (PK Links).
Todo el bloque de estilos del Lookbook (.lookbook-item,
.lookbook-products-list, .lookbook-image, .pois, etc.).

No parece que exista un error de sintaxis en el CSS, sino que durante
la generación del CSS combinado algunos recursos de Creative Elements
dejan de incluirse.

¿Podríais revisar si existe algún problema conocido entre la
combinación de CSS de Alysum y Creative Elements, o si hay algún
proceso de caché que pueda provocar que no se añadan todos los estilos
al CSS generado?

Si necesitáis, adjunto tanto el CSS correcto como el CSS incorrecto
para que podáis compararlos.

Muchas gracias.

Hello,

We’re detecting a rather strange problem with CSS merging/minification in Alysum, and we’ve managed to narrow it down quite a bit.

Randomly (usually after a few hours or the next day), the homepage starts to look wrong. The two main symptoms are:

The Lookbook widget completely loses its layout, and the products appear jumbled together.
The PK Links/category widgets display bullets (list-style: disc), as if their specific styles aren’t loading.

If I regenerate the CSS from Creative Elements and then clear the cache for both Alysum and PrestaShop, everything looks correct again. However, after a while, it happens again even though no changes have been made.

I’ve compared the generated CSS and found a significant difference:

The correct CSS is approximately 263 KB.

The incorrect CSS is approximately 256 KB.

The faulty CSS is missing several complete blocks, including:

The specific styles for the .elementor-3010000 element

.elementor-element-164639b (PK Links).

The entire Lookbook style block (.lookbook-item,
.lookbook-products-list, .lookbook-image, .pois, etc.).

There doesn’t appear to be a syntax error in the CSS itself, but rather that during the generation of the combined CSS, some Creative Elements resources are being omitted.

Could you please check if there are any known issues with the combination of Alysum and Creative Elements CSS, or if there is a caching process that might be preventing all styles from being added to the generated CSS?

If needed, I can attach both the correct and incorrect CSS for you to compare.

Thank you very much.

Hi, JUAN CARLOS HUERTA.
It's hard to debug minified styled.
From my experience such problem happened when one of css file is invalid. We provide valid css files with the theme. So the problem could come from:
- third party modules
- your custom CSS code which you added in the Theme Settings → Customer CSS code

Hi,

Thank you for your reply.

We have already tested the possibilities you mentioned and can rule out our Custom CSS as the cause.

The issue has been reproduced:

- With our Custom CSS completely disabled.
- With CSS combination/minification disabled.
- After clearing the PrestaShop cache and regenerating Creative Elements assets.
- Before the additional third-party modules currently installed in the shop were added.
- On a different temporary server, where we performed the same tests and obtained the same intermittent behaviour.

Therefore, the issue does not appear to be specific to the current hosting environment either.

The behaviour is intermittent: the homepage can render correctly and later lose some styles without any changes being made.

We have also compared the working and faulty states. This does not appear to be a CSS syntax error causing the stylesheet to stop being parsed. Instead, complete CSS blocks required by Alysum/Promokit modules are sometimes loaded and sometimes missing.

For example, we have observed the styles for a Creative Elements template (".elementor-3010000") disappear, as well as generic styles required by "pklookbook" (".lookbook-item", ".lookbook-products-list", ".lookbook-image", ".pois", etc.).

When these styles are present, the homepage renders correctly. When they are missing, the affected elements lose their layout.

This suggests that there may be an issue with the way Alysum, Creative Elements and the Promokit modules register/load their assets, possibly related to the module or hook execution order, rather than an invalid Custom CSS file.

As a temporary workaround, we have copied the CSS rules that intermittently fail to load into Custom CSS. Therefore, these rules may sometimes be duplicated, but this prevents the live shop from appearing broken when the original module styles are missing.

At this point, we would appreciate it if you could investigate the issue directly on the installation and determine why these module styles are intermittently not being loaded.

You already have FTP and PrestaShop Back Office access to the shop, so please feel free to use them to debug the theme and module asset loading directly.
