Waqas Bin Hasan Supporter Languages: English (English ) Timezone: Asia/Karachi (GMT+05:00)	Hi, Thank you for contacting the support. Apparently the issue was fixed in WPML Sticky Links 1.5.4 as per this errata https://wpml.org/errata/wpml-sticky-links-deprecated-error-on-php-8-x/. However, may I ask you to try the following please? IMPORTANT: Please take full backup of your website and database beforehand. - Deactivate WPML Sticky Links plugin and delete it from plugins page. - Download from https://wpml.org/account/downloads/ and upload via Plugins -> Add New -> Upload. - Activate and recheck. If this does not resolve the issue, please check the above mentioned errata for a workaround and try that. Although that should already be in place but just to confirm if you don't see it, you can try it to fix the issue temporarily. Please let me know and I'll try my best to help you further on the matter. Regards.

dmitrijsH	Hello, Although it is marked as resolved, version 1.5.4 dates back to 2020. And the issue was reported for 1.5.4 (not resolved in 1.5.4). Could you please check whether the new version can be downloaded somehow. Kind regards,

dmitrijsH	The workaround has helped. But I am getting another deprecated thing linked to your plugin: [05-Aug-2024 13:28:34 UTC] PHP Deprecated: rtrim(): Passing null to parameter #1 ($string) of type string is deprecated in /home/.../public_html/wp-includes/formatting.php on line 2819

Waqas Bin Hasan Supporter Languages: English (English ) Timezone: Asia/Karachi (GMT+05:00)	Thank you for the updates. A new version of WPML Sticky Links plugin is due release, although there's no ETA so far but we hope to have it out soon. Until then you can keep the fix in place to avoid that notice and once the new version is available, you can simply upgrade to that. For the other deprecation notice, I checked and that's also part of several other deprecated notices due to PHP 8.x and new WordPress changes. These are also due in WPML 4.7 (no ETA so far but expected soon). So you can either check this thread https://wpml.org/forums/topic/deprecated-rtrim-passing-null-to-parameter-1-string-php-8-1-2/#post-13670953 for a temporary workaround, check our forums for another relevant solution, or, report in a separate ticket. Because as per forum policy we can only handle one issue per ticket/chat. So you can get more to the point help, without mixing up several issues in one long ticket.
