[Vtigercrm-developers] HTMLPurigier_Config not found error

[Martin Allen]

We had an issue with the vtlib_purify function recently (that appears in your stacktrace) – which prevented it working correctly if we had used any Composer packages prior to that function. It appears that the function tries to unload autoloaded items, but cant do this correctly when Composer has autoloaded items.
It doesn’t look like this is the issue in your case, unless something has triggered composers autoloader prior to this point in the code (we were using it in custom workflow functions).

Hi everyone,

I have a script that modifies and saves invoices. I had been running literally for years without problems.
Recently, this kind of error appeared:

Fatal error: Uncaught Error: Class 'HTMLPurifier_Config' not found in /var/www/html/vtigercrm/include/utils/VtlibUtils.php:686
Stack trace:
#0 /var/www/html/vtigercrm/include/utils/InventoryUtils.php(648): vtlib_purify('125559')
#1 /var/www/html/vtigercrm/modules/Invoice/Invoice.php(142): saveInventoryProductDetails(Object(Invoice), 'Invoice')
#2 /var/www/html/vtigercrm/data/CRMEntity.php(129): Invoice->save_module('Invoice')
#3 /var/www/html/vtigercrm/data/CRMEntity.php(940): CRMEntity->saveentity('Invoice', '')
#4 /var/www/html/vtigercrm/modules/Vtiger/models/Module.php(169): CRMEntity->save('Invoice')
#5 /var/www/html/vtigercrm/modules/Vtiger/models/Record.php(259): Vtiger_Module_Model->saveRecord(Object(Invoice_Record_Model))

I'm not the only person with access to the server, but as far as I can see and I was told, there have been no modifications to vtiger files recently.
Do you have any idea why this would happen?

Its a vtiger 7.1 using php 7.0

Saludos

Rubén
