Title: Combine JavaScript Files breaks Header Image Last modified: June 23, 2020 --- # Combine JavaScript Files breaks Header Image * Resolved [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 11 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/) * Hi There * I have a Uncode Theme which uses Content Blocks to populate the header in pages. * The plugin works fine in all aspects except for Combine JavaScript Files. When I enable this the images on the header do not show up. Just the title with a black background. I’ve tried excluding the content block url and the Image itself but that doesn’t work even though the test shows it as not cached. * It looks fine if you view the site via WordPress admin but on the live site it is broken. * Any ideas on how to rectify this. It’s killing my load time on Mobile and Core web vitals show all my urls are poor! * I’ve not activated Combine JavaScript Files at the moment because the visitor experience is poor with it on. * Many thanks * Andy * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcombine-javascript-files-breaks-header-image%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 14 replies - 1 through 14 (of 14 total) * Plugin Author [Stanimir Stoyanov](https://wordpress.org/support/users/sstoqnov/) * (@sstoqnov) * SiteGround Representative * [5 years, 11 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13023809) * Hey [@andybritnell](https://wordpress.org/support/users/andybritnell/) * It’s a known issue between SG Optimizer and Undsgn themes/plugins. * We are currently working on it, and we will try to include a fix in the upcoming version. * Meanwhile, please keep Combine JS disabled. * Regards, Stanimir * Thread Starter [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 11 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13024140) * Hi Stanimir * Ok thanks for that information – looking forward to getting a fix on it 🙂 * Best wishes * Andy * Plugin Author [Stanimir Stoyanov](https://wordpress.org/support/users/sstoqnov/) * (@sstoqnov) * SiteGround Representative * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13098509) * Hey [@andybritnell](https://wordpress.org/support/users/andybritnell/) * We’ve fixed everything related to our plugin, and we will release a new version soon. I think that the JS combination will work for sites using Uncode themes. * But, there is one small thing that you should request from Uncode team to address: * They should change the following condition: `if ( elem !== null && typeof elem. classList !== 'undefined' )` * TO: `if ( elem !== undefined && typeof elem.classList !== 'undefined' )` * Because if an element doesn’t exist, it will return `undefined` instead of `null`. * Regards, Stanimir * Thread Starter [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099712) * Hi Stanimir * My ‘helpful’ Uncode team came back with this! * Hi Andy, * You have to do yourself and ask them clear instructions where to change or hire a developer who can do this for you. Imran | Undsgn™ Support * So can you let me know where specifically I change this code and if I need to wait for the fix before changing it. * Many thanks * Andy * Plugin Author [Stanimir Stoyanov](https://wordpress.org/support/users/sstoqnov/) * (@sstoqnov) * SiteGround Representative * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099737) * Hey [@andybritnell](https://wordpress.org/support/users/andybritnell/) * They should change the line I mentioned in my previous reply in themes/uncode/ library/js/unit.js on line 565, 568, 571, 575, 579, and 583. * Hope this will help 🙂 * Regards, Stanimir * Thread Starter [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099750) * Hi Stanimir * OK – thanks for the info – I’ll hold back until you update the plugin and then make the change. * Many thanks * Andy * Plugin Author [Stanimir Stoyanov](https://wordpress.org/support/users/sstoqnov/) * (@sstoqnov) * SiteGround Representative * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099752) * Hey [@andybritnell](https://wordpress.org/support/users/andybritnell/) * We’ve released a new version few seconds ago 🙂 * Regards, Stanimir * Thread Starter [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099762) * Ok Cool * Just updating it now. * Will let you know if it fixes thngs 🙂 * Bets wishes * Andy * Plugin Author [Stanimir Stoyanov](https://wordpress.org/support/users/sstoqnov/) * (@sstoqnov) * SiteGround Representative * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099769) * Please note that the file init.js is minified when the Uncode team release a new version and the minified copy is located in themes/uncode/library/js/min/ unit.min.js * Thread Starter [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099783) * Hi Stanimir * I checked the site without updating code and it’s working without changing any code so good work from your team fixing that. * You can check it out at [https://www.dennismaps.co.uk/](https://www.dennismaps.co.uk/) * Full marks for problem solving and customer service. * Best wishes * Andy * Thread Starter [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099905) * Hi Stanimir * Does that mean even though it works I still need to make the code changes? * Many thanks * Andy * Plugin Author [Stanimir Stoyanov](https://wordpress.org/support/users/sstoqnov/) * (@sstoqnov) * SiteGround Representative * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13099972) * Hey [@andybritnell](https://wordpress.org/support/users/andybritnell/), * Well, there is an error in the console, which doesn’t break the site or its functionality, but it will be nice if the Uncode team fixes their code. * I do not recommend making changes of plugins/themes because when a new version is released, everything will be removed after an update. * Regards, Stanimir * Thread Starter [andybritnell](https://wordpress.org/support/users/andybritnell/) * (@andybritnell) * [5 years, 10 months ago](https://wordpress.org/support/topic/combine-javascript-files-breaks-header-image/#post-13100123) * Hi Stanimir * Agreed they really should pull there finger out a bit more!
