Payment of a customer invoice is not working anymore in version 14.0.4. After filling in the paid amount and press “Pay” it returns an ERROR 500 Did anyone have this problem and how can it be solved? /erp/htdocs/compta/paiement.php Regards, Davy ---

Don’t know, how and where dolibarr is installed ? Blank windows on settings/modules can also come from an external module, can you remove them all ? What PHP version are you using ? ---

Hello, I am using PHP 8.0.13. Dolibarr is installed on my webspace under /erp/htdocs. I have been upgrading for several years. Uploading the new dolibarr files and run the install. Only since upgrade to version 14 there are some problems. But only discovered several issues today. All external modules have been removed. Problem still persists. - erp/htdocs/admin/modules.php?mainmenu=home = blank page - erp/htdocs/admin/dict.php?mainmenu=home = ERROR 500 - After some testing I found out that only invoices from a specific customer cannot be paid and return an ERROR 500 ---

hello, User since a few years with Dolibarr 13 for a french company ( invoices and accounting ), i would like to use Dolibarr for an Irish ltd company, but i don’t know the basis requirements for accounting in Ireland. Could you tell me what i need to install for accounting, because i suppose that except adjusting VAT and some parameters, there are no change for invoices ! Thanks DL
