Hello/Hi/Greetings,

I have change php.ini for larger upload_max_files and post_max_files (and then later back to original). Since then I cannot upload any photos. I thought it might be a piwigo issue so I updated to the latest version (13). Still the same error as such:

Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in /var/www/html/piwigo/_data/templates_c/p6jhns^7ad44899ce7afaddc90cc815918b43b243683bb5_0.file.photos_add_direct.tpl.php:551 Stack trace: #0 /var/www/html/piwigo/include/smarty/libs/sysplugins/smarty_template_resource_base.php(123): content_633d73aa429950_97742996() #1 /var/www/html/piwigo/include/smarty/libs/sysplugins/smarty_template_compiled.php(114): Smarty_Template_Resource_Base->getRenderedTemplateCode() #2 /var/www/html/piwigo/include/smarty/libs/sysplugins/smarty_internal_template.php(216): Smarty_Template_Compiled->render() #3 /var/www/html/piwigo/include/smarty/libs/sysplugins/smarty_internal_templatebase.php(238): Smarty_Internal_Template->render() #4 /var/www/html/piwigo/include/smarty/libs/sysplugins/smarty_internal_templatebase.php(116): Smarty_Internal_TemplateBase->_execute() #5 /var/www/html/piwigo/include/template.class.php(469): Smarty_Internal_TemplateBase->fetch() #6 /var/www/html/piwigo/include/template.class.php(392): Template->parse() #7 /var/www/html/piwigo/admin/photos_add_direct.php(156): Template->assign_var_from_handle() #8 /var/www/html/piwigo/admin/photos_add.php(73): include('...') #9 /var/www/html/piwigo/admin.php(320): include('...') #10 {main} thrown in /var/www/html/piwigo/_data/templates_c/p6jhns^7ad44899ce7afaddc90cc815918b43b243683bb5_0.file.photos_add_direct.tpl.php on line 551
