Hello, I’ve been using Dolibarr for several years and updating it without issues from vers 3.4.2 to vers 10.0.3 (several updates since I installed it, when these version were released). Now I’m stuck in this version because everytime I try to adpdate to 10.0.7, or above the update works fine (only two minor issues with to tables I can solve via phpmyadmin), but when log into Dolibarr everything works fine except two screens; proposals (Presupuestos, I have the spanish version) and orders (Pedidos). The screen is totally blank. All the other parts and screens of the progams work fine. This is a capture of how the screen loooks like. ![image](https://www.dolibarr.org/forum/uploads/dolibarrorg/original/2X/9/9801802093cd5d397c0990ba8ea5b66de9639d67.png) Dolibarr vers: 10.0.3 -\> 12.0.3 Apache 2.4.41 PHP 7.4.3 MySQL 8.0.21 Ubuntu 20.04.1 LTS Regards ---

Hi, Blank means php error. Please have a look to Apache logs ---

Thank you for your quick answer Ksar.

Sorry Ksar, I forgot the /var/log/apache2/error.log: [Mon Oct 12 13:00:25.110364 2020] [php7:error] [pid 348479] [client 192.168.XXX.XXX:4921] PHP Fatal error: Uncaught Error: Unsupported operand types in /usr/share/dolibarr/htdocs/core/class/hookmanager.class.php:257\nStack trace:\n#0 /usr/share/dolibarr/htdocs/core/lib/functions.lib.php(7585): HookManager-\>executeHooks()\n#1 /usr/share/dolibarr/htdocs/core/lib/order.lib.php(83): complete\_head\_from\_modules()\n#2 /usr/share/dolibarr/htdocs/commande/card.php(1926): commande\_prepare\_head()\n#3 {main}\n thrown in /usr/share/dolibarr/htdocs/core/class/hookmanager.class.php on line 257, referer: [http://192.168.XXX.XXX/dolibarr/commande/list.php?leftmenu=orders](http://192.168.XXX.XXX/dolibarr/commande/list.php?leftmenu=orders) Regards. ---

HI, The error is related to hookmanager =\> Have you external module installed ? ---

Finally I’ve found the solution. As is described in the error.log file there is an error en the line 257 of the file /usr/share/dolibarr/htdocs/core/class/hookmanager.class.php. There were an operand +=, I’ve replaced this operand by == and now dolibarr works fine! Thans Ksar for your clue about php errors Regards ---

Hi, Sorry but no it is not supposed to work like that. The line 257 must be like that : ```php $resaction += $actionclassinstance->$method($parameters, $object, $action, $this); // $object and $action can be changed by method ($object->id during creation for example or $action to go back to other action for example) ``` Remember if you are on line 257, that’s means the Hook type “addreplace” should return an int If it fails, means that a hook on your system doesn’t return an int. So You have a “bad” external module installed. ---

Hi, Thanks again. Yes, you were right, it was an old module (Doliconta) the root cause. I’ve deactivated it and restored the line 257 and everything works fine. Regards.
