Title: Sudden LS Error Last modified: December 23, 2024 --- # Sudden LS Error * Resolved [Chad](https://wordpress.org/support/users/chadi/) * (@chadi) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/) * I had to manually delete the LS plugin today when I saw an error on my site trying to log into the admin panel, got the critical error message. * Then, error log file shows this: * ```wp-block-code [23-Dec-2024 14:22:24 UTC] PHP Fatal error: Uncaught Error: Call to a member function has() on null in /home/user/public_html/wp-includes/l10n.php:1359Stack trace:#0 /home/user/public_html/wp-includes/l10n.php(1408): _load_textdomain_just_in_time('litespeed-cache')#1 /home/user/public_html/wp-includes/l10n.php(194): get_translations_for_domain('litespeed-cache')#2 /home/user/public_html/wp-includes/l10n.php(306): translate('Redis encounter...', 'litespeed-cache')#3 /home/user/public_html/wp-content/plugins/litespeed-cache/src/object-cache.cls.php(500): __('Redis encounter...', 'litespeed-cache')#4 /home/user/public_html/wp-content/plugins/litespeed-cache/src/object.lib.php(736): LiteSpeed\Object_Cache->set('a0720options.al...', 'a:1:{s:4:"data"...', 0)#5 /home/user/public_html/wp-content/plugins/litespeed-cache/src/object.lib.php(628): WP_Object_Cache->set('alloptions', Array, 'options', 0)#6 /home/user/public_html/wp-content/plugins/litespeed-cache/src/object.lib.php(53): WP_Object_Cache->add('alloptions', Array, 'options', 0)#7 /home/user/public_html/wp-includes/option.php(641): wp_cache_add('alloptions', Array, 'options')#8 /home/user/public_html/wp-includes/functions.php(1780): wp_load_alloptions()#9 /home/user/public_html/wp-includes/load.php(914): is_blog_installed()#10 /home/user/public_html/wp-settings.php(175): wp_not_installed()#11 /home/user/public_html/wp-config.php(86): require_once('/home/user/...')#12 /home/user/public_html/wp-load.php(50): require_once('/home/user/...')#13 /home/user/public_html/wp-blog-header.php(13): require_once('/home/user/...')#14 /home/user/public_html/index.php(17): require('/home/user/...')#15 {main} thrown in /home/user/public_html/wp-includes/l10n.php on line 1359 ``` * When I reinstalled the plugin, the error came back and couldn’t log into the admin panel. Everything was working just fine, unchanged config for weeks until this morning. Maybe an auto update? How can I fix this? Usually, deleting plugin allows to reinstall and fix that error, not in this case.

I did mention twice that I cannot access WP admin panel when Litespeed plugin is activated, due to the error “There has been a critical error on this website.”. That’s the whole issue and point of this ticket. - This reply was modified 1 year, 5 months ago by [Chad](https://wordpress.org/support/users/chadi/). * Thread Starter [Chad](https://wordpress.org/support/users/chadi/) * (@chadi) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18214154) * Hello, * I’m on WP Version 6.7.1. and LS server version is 6.3.1 (build 7) * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18214172) * [@chadi](https://wordpress.org/support/users/chadi/) thank you! Looking over the WP code, it seems that the problem comes from another source.It overrides a WP default variable, that will be used in translation.Searching Google a little bit I see 2 similar situations where users had problems with older version of WPML: [https://wordpress.org/support/topic/fatal-error-with-wp-6-1/](https://wordpress.org/support/topic/fatal-error-with-wp-6-1/) or [https://stackoverflow.com/questions/74287781/call-to-undefined-method-wp-textdomain-registryreset](https://stackoverflow.com/questions/74287781/call-to-undefined-method-wp-textdomain-registryreset) The functions are different, but they use the same class. * Waiting on your answer 🙂 * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18214179) * It you don’t use WPML, think about other plugin that changes/adds translation. * If you require in depth support, you can open a ticket by sending a mail to ` support at [litespeedtech.com](http://litespeedtech.com/)` with reference link to this topic * Thread Starter [Chad](https://wordpress.org/support/users/chadi/) * (@chadi) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18214180) * Thanks, but I do not have that plugin installed nor did.

There is another test you can do: leave LSC enabled and disable plugin one by one, at least we rule out your plugins.The theme is Copler? * Thread Starter [Chad](https://wordpress.org/support/users/chadi/) * (@chadi) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18214960) * The theme is copler yes. All these plugins worked together for over a year.

What updated in last 2 days? What changes have been applied to server? * [imagophilos](https://wordpress.org/support/users/imagophilos/) * (@imagophilos) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18221540) * Sorry to say, but we got the exact same error. No wpml used, only Loco Translate, and it’s not Loco’s fault, we verified. WordPress was updated weeks ago, no other update has been made recently. Yesterday this error showed in the log and the frontend was blocked on 503 for hours with 100% CPU on LiteSpeed server. * Report: **RJKWYLDN** * I’m really sorry, but Litespeed starts to be a true pain. Every few days it throws a 100% CPU, blocking everything. Every time we have to select “Disable all features”, leave it like that for a few minutes and then the frontend starts working again. Nothing helps. Disabling plugins, switching themes, full purge, resetting LSCache… Sometimes we need to kill the lsph processes manually on the servers terminal. * Beside an unrelated error, only LS errors show on logs, we are a bit out of options here. Add to this the constant seemingly random purges (with all settings correct, double and triple verified), we start to question what the utility of Litespeed is… Really angry over here. Sorry for this. * Thread Starter [Chad](https://wordpress.org/support/users/chadi/) * (@chadi) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18221628) * Same here. Still not working. It’s specifically the LiteSpeed plugin, nothing else. * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18221733) * I will look into this as soon as I get from New Year holiday 🙁 We are so sorry about the problems you encounter. * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18221749) * [@chadi](https://wordpress.org/support/users/chadi/) quick thing to test: can you disable Redis cache on plugin? From here: [https://docs.litespeedtech.com/lscache/lscwp/cache/#object-cache](https://docs.litespeedtech.com/lscache/lscwp/cache/#object-cache) * Thread Starter [Chad](https://wordpress.org/support/users/chadi/) * (@chadi) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18221783) * As I have mentioned a few times and specifically opened this ticket about, the plugin is not installed due to the error and inability to access admin panel when plugins IS installed. * Plugin Support [litetim](https://wordpress.org/support/users/litetim/) * (@litetim) * [1 year, 5 months ago](https://wordpress.org/support/topic/sudden-ls-error/#post-18222087) * [@chadi](https://wordpress.org/support/users/chadi/) rename from FTP(Cpanel,SSH) the file: **/public_html/wp-content/advanced-cache.php** to somethings else, just to have a backup of that file. It does not matter, it will be recreated if needed.
