Error: "No decimal pattern found for numbering system"

[psauleda]

Hello.

This morning I have disabled imageslider module on a 1.7 prestashop.

After that, I don't remember exactly if I disabled banner module or just tried to enter its configuration, but anyway the site crashed.

On debug mode it says:

CRITICAL 13:00:38     php     Uncaught Exception: No decimal pattern found for numbering system:
CRITICAL 13:00:38     request     Uncaught PHP Exception PrestaShop\PrestaShop\Core\Localization\Exception\LocalizationException: "No decimal pattern found for numbering system: " at /var/www/MYPATH/MYSITE/src/Core/Localization/CLDR/Locale.php line 212

Looking at google, some people solved it by deleting cache. But after deleting /var/cache/dev and /var/cache/prod, I still have the error.

No decimal pattern found for numbering system:

After colon, it should display the value of `$numberingSystem`

 

Function explanation about $numberingSystem :
If null, the default numbering system of this locale will be used.

/**
     * Get the number symbols to use for a given numbering system.
     *
     * @param string|null $numberingSystem
     *                                     The numbering system of the wanted symbols set.
     *                                     If null, the default numbering system of this locale will be used.
     *
     * @return NumberSymbolsData
     *                           The wanted number symbols
     *
     * @throws LocalizationException
     *                               When passed $numberingSystem is invalid
     */
    public function getNumberSymbolsByNumberingSystem($numberingSystem = null)
    {
        if (null === $numberingSystem) {
            $numberingSystem = $this->getDefaultNumberingSystem();
        }
        if (!isset($this->getAllNumberSymbols()[$numberingSystem])) {
            throw new LocalizationException('Invalid numbering system: ' . $numberingSystem);
        }

        return $this->getAllNumberSymbols()[$numberingSystem];
    }

 

Maybe check files / data related to locale 
OR functions related to disabling / configuring imageslider 

Could it be cached on hosting side?

At worst, reimport locale to the system

Thanks for your help. 

Finally I decided to restore a backup, upgrade from 1.7.8.5 to 1.7.8.8 and problems seem to have gone, I can disable both modules without problems.
