Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Thank you for your clarification. I ran several troubleshooting steps, but the issue persists, even in a minimal setup. I would like to ask your authorization to create a copy of the site to send it to our 2nd tier of suppor,t where our specialists will take a deeper look.

rhettY	Can you do it on the test site? You can run any test and modify anything there.

Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi, I already ran all the possible tests on the staging site. My colleagues on the 2nd-tier need a copy of the site to run further tests in a controlled environment, which is the reason why we need a copy.

rhettY	Ok. I have no choice. Please go ahead

rhettY	Thanks. You may have your team check this ticket too: https://wpml.org/forums/topic/php-fatal-error-uncaught-invalidargumentexception-4/ It's not solved yet: 1. sitekey not found, though I've unregistered and re-registered several time. 2. PHP Fatal error: Uncaught InvalidArgumentException: Argument $language_code must be a non empty string.

Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi, Please disable the cache memory and contact your hosting providers to disable any cache memory that might exist on the server-side. Then double-check if the issue persists and let me know, so we can run more tests with the cache memory disabled.

rhettY	Just disabled all cache memory in racinghobby.com site. The currency switcher issue disappears. Please check. Cache is important for my site. Please solve the issue.

Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Thank you for your message. Please add the admin-ajax.php to the cache exclude list in the LiteSpeed settings and check if the issue disappears.
September 24, 2025 at 9:51 am #17428365
rhettY	I added admin-ajax.php in cache -> excludes -> Do Not Cache URIs. And enabled all cache memory. The issue comes back. The flags also do not display. Formerly after disabling cache, they display

Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi, As described in the Litespeed settings, you must add the URIs, not the name of the file. I recommend contacting the support service of Litespeed to correctly exclude the admin-ajax.php file
September 24, 2025 at 10:01 am #17428404
rhettY	Please check this file: hidden link I modified it to "/admin-ajax.php". This should be the correct setting.

Carlos Rojas WPML Supporter since 03/2017 Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi, I created a quick video: hidden link showing that the currency switcher is working now and recommending some steps to fix the flags issue
September 24, 2025 at 10:35 am #17428658
rhettY	I noticed you also need to click twice the default currency. Please check. In fact I've figured out a way to solve the flag display issue. I excluded the media by adding the media classes in the media cache exlusion in litespeed.
