Hi Damyan, Thanks for your follow-up!

It can be reproduced easily. Just use a standard Apache installation with libapache2-mod-php7.3, place the translate.php in the document root and create the locale structure in the same path as translate.php: ./locale/de_CH.UTF-8/LC_MESSAGES/ Inside LC_MESSAGES place a homepage.po file, here's an example: ------- cut ------- # Sample translation. # Copyright (C) 2020 Infiniroot. # Infiniroot LLC <[email protected]>, 2020. # #, fuzzy msgid "" msgstr "" "Project-Id-Version: Infiniroot 1.0\n" "Report-Msgid-Bugs-To: \n" "POT-Creation-Date: 2020-11-16 10:00+0100\n" "PO-Revision-Date: 2020-11-16 10:00+0100\n" "Last-Translator: Infiniroot <[email protected]>\n" "Language-Team: Infiniroot <[email protected]>\n" "MIME-Version: 1.0\n" "Content-Type: text/plain; charset=UTF-8\n" "Content-Transfer-Encoding: 8bit\n" "Language: de\n" "Plural-Forms: nplurals=2; plural=(n != 1);\n" # Home page msgid "Dedicated Hosting Description" msgstr "Mein deutscher Text" ------- cut ------- Then use msgfmt command (from the gettext package) to create a binary mo file: cd locale/de_CH.UTF-8/LC_MESSAGES/; msgfmt homepage.po --output-file=homepage.mo -v When you now launch the translate.php file through Apache (you can use curl), it should translate and show the German translation. $ curl localhost/translate.php Mein deutscher Text Then install and enable the libapache2-mod-perl2 module and restart Apache. The translation stops working. $ curl localhost/translate.php Original English was returned. Something wrong I published a blog article about this behaviour yesterday: https://www.claudiokuenzler.com/blog/1023/php-gettext-translations-not-working-apache-mod_php-cli-works. The sample translate.php is included in the article. Hope this helps. Am available for debugging this together if you want.
