Title: Warning: Illegal string offset 'theme_advanced_font_sizes' Last modified: August 21, 2016 --- # Warning: Illegal string offset 'theme_advanced_font_sizes' * Resolved [blizcreak](https://wordpress.org/support/users/blizcreak/) * (@blizcreak) * [12 years, 3 months ago](https://wordpress.org/support/topic/warning-illegal-string-offset-theme_advanced_font_sizes/) * Getting this warning message when running Ultimate TinyMCE 5.2 on WordPress 3.8.1 with PHP 5.4 * I suspect that it is an incompatibility with PHP 5.4 * The full warnings are: * Warning: Illegal string offset ‘theme_advanced_font_sizes’ in /home/virtualw/ public_html/wordpress/wp-content/plugins/ultimate-tinymce/admin_functions.php on line 40 * Warning: Illegal string offset ‘plugin_insertdate_dateFormat’ in /home/virtualw/ public_html/wordpress/wp-content/plugins/ultimate-tinymce/admin_functions.php on line 41 * Warning: Illegal string offset ‘plugin_insertdate_timeFormat’ in /home/virtualw/ public_html/wordpress/wp-content/plugins/ultimate-tinymce/admin_functions.php on line 42 * Warning: Illegal string offset ‘wordpress_adv_hidden’ in /home/virtualw/public_html/ wordpress/wp-content/plugins/ultimate-tinymce/admin_functions.php on line 44 * Warning: Illegal string offset ‘content_css’ in /home/virtualw/public_html/wordpress/ wp-content/plugins/ultimate-tinymce/options_functions.php on line 1065 * Hope you can fix, as I had to disable the plugin 🙁 * Thanks * Noel * [https://wordpress.org/plugins/ultimate-tinymce/](https://wordpress.org/plugins/ultimate-tinymce/) Viewing 10 replies - 1 through 10 (of 10 total) * Thread Starter [blizcreak](https://wordpress.org/support/users/blizcreak/) * (@blizcreak) * [12 years, 3 months ago](https://wordpress.org/support/topic/warning-illegal-string-offset-theme_advanced_font_sizes/#post-4686832) * Adding the line 39 * ``` $initArray = array(); ``` * to admin_functions.php seems to do the trick. * Noel * Plugin Author [Josh](https://wordpress.org/support/users/josh401/) * (@josh401) * [12 years, 3 months ago](https://wordpress.org/support/topic/warning-illegal-string-offset-theme_advanced_font_sizes/#post-4686835) * Hi Noel, Yes, it’s because of php 5.4. * Your solution may have some adverse affects… because you are basically erasing anything that’s being passed into the function argument by redeclaring the variable as an empty array. * Instead, we should first check if the variable is empty.. and then add our items. * Replacing the entire function (and filter) with this one: [http://pastebin.com/jxukNy7c](http://pastebin.com/jxukNy7c) * .. should resolved the issue on a more localized approach. * Thread Starter [blizcreak](https://wordpress.org/support/users/blizcreak/) * (@blizcreak) * [12 years, 3 months ago](https://wordpress.org/support/topic/warning-illegal-string-offset-theme_advanced_font_sizes/#post-4686839) * Thanks Josh, * Just tried that, but it doesn’t work – gives the same errors, as it still has the problem that * ``` if(empty($initArray['theme_advanced_font_sizes'])) { ``` * expects $initArray to be an array when it is, in fact, a string with the value string(16) “nice_mce_options” * So, either we need to feed an actual array into the function, or we need to redefine $initArray as an array as the first line inside the function. * Noel * Plugin Author [Josh](https://wordpress.org/support/users/josh401/) * (@josh401) * [12 years, 3 months ago](https://wordpress.org/support/topic/warning-illegal-string-offset-theme_advanced_font_sizes/#post-4686843) * Okay, thanks for trying. * $initArray is an array. Here is a var_dump of my $initArray variable before it is modified: [http://pastebin.com/SK7Q4Agu](http://pastebin.com/SK7Q4Agu) * You can see it does not contain a [‘theme_advanced_font_sizes’] key. * Perhaps instead of checking if is empty.. we should check if exists. * I have to step out for a meeting. I’ll be back in about an hour. I’ll set up php 5.4 on my test server when I get back home so I can replicate the warnings. * From there… I should be able to provide a better solution. * Thank you.. VERY much… for your time! * Plugin Author [Josh](https://wordpress.org/support/users/josh401/) * (@josh401) * [12 years, 2 months ago](https://wordpress.org/support/topic/warning-illegal-string-offset-theme_advanced_font_sizes/#post-4687032) * Sorry.. got overwhelmed. * I’ll address this tomorrow.

Isn’t that ironic?? * I’m checking it out on my local install now. I, just tonight, updated my xampp to PHP 5.5.9… to ensure everything is running properly on the new converted WP Edit plugin. * Let me check it out and I’ll be right back. * EDIT: I’m not seeing the notices.
