Title: Javascript syntax error in version 7.0 Last modified: November 12, 2021 --- # Javascript syntax error in version 7.0 * Resolved [christer_f](https://wordpress.org/support/users/christer_f/) * (@christer_f) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/) * Hi Aakash, * Today I updated your plugin on a site from version 6.4 to 7.0 and I’m now getting Javascript errors from wp-socializer.min.js. I switched to the non-minified version and found that the error appears on line 486. Error message: * “SyntaxError: Invalid regular expression: invalid group specifier name” * Then I put single quotes around the regular expression, and the error message goes away (but maybe this may cause other problems??) * — christer - This topic was modified 4 years, 6 months ago by [christer_f](https://wordpress.org/support/users/christer_f/).

Looking at the error I guess it is something specific to safari browser. * Can you please check once in Chrome and share your website URL where error is observed ? I would like to see the issue live. * Thanks, Aakash * Thread Starter [christer_f](https://wordpress.org/support/users/christer_f/) * (@christer_f) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/#post-15063016) * Thanks for your very quick reply! * No problem in Chrome! * I did the update on my local development system (I always do that before doing updates to a production environment), which is not accessible from the outside. I don’t want to update the production environment now since a Javascript error will impact other things, but I can copy over to a staging server. Will take some 30 minutes. I’ll send you the URL when it’s done * Thread Starter [christer_f](https://wordpress.org/support/users/christer_f/) * (@christer_f) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/#post-15063237) * This is the URL to the staging server: * [https://aravis.chrilleferna.opalstacked.com](https://aravis.chrilleferna.opalstacked.com) * I have switched to the unminified version of wp-socializer.js so you can see on which line the problem shows up * Thread Starter [christer_f](https://wordpress.org/support/users/christer_f/) * (@christer_f) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/#post-15064270) * Hi Aakash, Any news on this? I quick Google search tells me that this problem is due to Safari not supporting lookbehind in javascript regular expressions. This means that even when/if Safari starts supporting lookbehind the code will break in older browsers, so better change the regex to one without lookbehind. * Plugin Author [vaakash](https://wordpress.org/support/users/vaakash/) * (@vaakash) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/#post-15064367) * Hi [@christer_f](https://wordpress.org/support/users/christer_f/), * I’m working on the issue. I’ll provide a workaround (i.e a code change) which you can make. Once I’m done testing I’ll share it with you. * Thanks, Aakash * Plugin Author [vaakash](https://wordpress.org/support/users/vaakash/) * (@vaakash) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/#post-15064403) * Hi [@christer_f](https://wordpress.org/support/users/christer_f/), * Please find the modified code below. [https://pastebin.com/bg8sFeey](https://pastebin.com/bg8sFeey) * Copy and paste it to wp-socializer/public/js/wp-socializer.js Refresh browser/ cdn cache if required. * This is not the the minified version. For now please continue with this. I’ll cover this issue as a part of the next release by next month mid. * Thanks, Aakash * Thread Starter [christer_f](https://wordpress.org/support/users/christer_f/) * (@christer_f) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/#post-15064654) * Hi Aakash, * Works fine! * Thanks you SO much for your quick and accurate fix. * Cheers, — christer * Plugin Author [vaakash](https://wordpress.org/support/users/vaakash/) * (@vaakash) * [4 years, 6 months ago](https://wordpress.org/support/topic/javascript-syntax-error-in-version-7-0/#post-15065100) * Cheers !
