Today a perform a migration of a Joomla 3.8 site from a server to another. All works well except only one custom module. The module works correctly before the migration but after the migration the error received is this one:
2022/05/04 17:15:23 [error] 2572#0: *1 FastCGI sent in stderr: "PHP message: PHP Fatal error: Cannot declare class PdfToJpg, because the name is already in use in /www/wwwroot/readeat.it/Joomla/modules/mod_readeat_menu_upload/mod_readeat_menu_upload.php on line 7" while reading response header from upstream, client: 84.33.118.182, server: readeat.it, request: "POST /index.php/it/il-mio-locale/carica-menu HTTP/2.0", upstream: "fastcgi://unix:/tmp/php-cgi-74.sock:", host: "test.readeat.it", referrer: "https://test.readeat.it/index.php/it/il-mio-locale/carica-menu"
The old server was a built-in server with Plesk Obsidian and Apache server, now i migrate all to a NGinx based server. The version of PHP is 7.4 in both scenarios.
