<b>Background of the issue: </b>
I am trying to add some custom CSS to my website. I navigated to Appearance > Customize > Additional CSS. The issue can be seen on this page: hidden link.
<b>Symptoms: </b>
I expected the right side of the screen to be blank, indicating no errors. Instead, I got a fatal error: Fatal error: Uncaught TypeError: array_intersect_key(): Argument #1 ($array) must be of type array, bool given in /var/www/html/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-templates.php:73 Stack trace: #0 /var/www/html/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-templates.php(73): array_intersect_key() #1 /var/www/html/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-assets.php(41): WPML_LS_Templates->get_templates() #2 /var/www/html/wp-includes/class-wp-hook.php(324): WPML_LS_Assets->wp_enqueue_scripts_action() #3 /var/www/html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters() #4 /var/www/html/wp-includes/plugin.php(517): WP_Hook->do_action() #5 /var/www/html/wp-includes/script-loader.php(2263): do_action() #6 /var/www/html/wp-includes/class-wp-customize-manager.php(462): wp_enqueue_scripts() #7 /var/www/html/wp-includes/class-wp-customize-manager.php(561): WP_Customize_Manager->wp_die() #8 /var/www/html/wp-includes/class-wp-hook.php(324): WP_Customize_Manager->setup_theme() #9 /var/www/html/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters() #10 /var/www/html/wp-includes/plugin.php(517): WP_Hook->do_action() #11 /var/www/html/wp-settings.php(630): do_action() #12 /var/www/html/wp-config.php(122): require_once('...') #13 /var/www/html/wp-load.php(50): require_once('...') #14 /var/www/html/wp-blog-header.php(13): require_once('...') #15 /var/www/html/index.php(20): require('...') #16 {main} thrown in /var/www/html/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-templates.php on line 73.
<b>Questions: </b>
How can I resolve the fatal error caused by WPML when adding custom CSS?
Is there a workaround to prevent WPML from interfering with my website's CSS rendering?
I apologize for the issue you encountered with this.
Are you having the issue if you remove your custom CSS?
Also, please try deactivating the "Disable cache for language switcher templates" option in the WPML → Support → Troubleshooting link and check if the issue persists.
Remember to back up your database before making any changes.
I need to request temporary access (wp-admin and FTP) to your site – preferably to a test site where the problem has been replicated if possible – in order to be of better help. You will find the needed fields for this below the comment area when you log in to leave your next reply. The information you will enter is private which means only you and I can see and have access to it.
Thank you for providing the information. Can you please direct me to the specific site I should check? I've noticed that it's a multisite and the site I logged into WPML is not configured.
There is still a WPML error. Though what did you change to make the failure message go away.
To reproduce the error, open an icognito browser and browse to hidden link and the home page renders fine. Then browse elsewhere (eg :cnn.com) and then browse back to hidden link
Now the layout boxes stack vertically instead of horizontally, box borders are missing, icons on the scroller down below are stacking overlapping, scroller no longer works, etc. If you browse to hidden link vs hidden link you get different results. My CSS no longer loads properly, javascript seems to have problems.
All of this stems from the WPML plugin. Something is still very wrong. Very briefly when the home page first loads, there is a PHP error, something about string to array. But it dissappears in under a second. I don't see this with WPML off....I think this is a clue.
It seems that the error is not in the admin but elsewhere. Could you please provide screenshots? Does the issue occur when you add custom CSS? Have you also added custom CSS to other languages by switching the language in the dashboard (on the theme options page)?
If you browse directly to the website with the language suffix (hidden link ) then the site renders correctly as shows in attached images good1 and good2.
If you browse to the website without language suffix (hidden link ) then the site renders incorrectly as shown in images bad1 and bad2.
Somehow the WPML plugin/redirection/code is causing the site to malfunction. I don't think its CSS related, since I moved the entire site to a new host (running more recent wordpress + php), and then the problem appeared. All worked fine on the old host. And since the buy occurs only with WPML redirection/language suffix on the URL all signs point to WPML.
