Title: Plugin causing console error: SyntaxError: missing ) after argument list Last modified: February 26, 2021 --- # Plugin causing console error: SyntaxError: missing ) after argument list * Resolved [Carl Gross](https://wordpress.org/support/users/carlgross/) * (@carlgross) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/) * Hello. I have the plugin enabled on my site, and on every page–including my home page–it is displaying the ‘protected by reCAPTCHA’ logo. I now have an error in the JavaScript console on my homepage: * `Uncaught SyntaxError: missing ) after argument list` * [sreenshot](https://i.imgur.com/VUGcIS5.jpeg). * This seems to be related to the CF7 plugin. I say that because when I deactivate the plugin, the error is not displayed. When I reactivate the plugin, the error returns. How can I resolve this? * I’ve seen other posts with people having a similar issue ([example](https://github.com/WordPress/gutenberg/issues/13029)). But it seems like in all those cases, the issue was due to a particular plugin/ theme, and fixed only after an update by said plugin/theme. * I am using version v5.4 of the plugin. * Thanks in advance. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-causing-console-error-syntaxerror-missing-after-argument-list%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 13 replies - 1 through 13 (of 13 total) * Plugin Author [Takayuki Miyoshi](https://wordpress.org/support/users/takayukister/) * (@takayukister) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14106618) * What other plugins and theme do you use on the site? * [Marcelo F.](https://wordpress.org/support/users/waltoslaguna/) * (@waltoslaguna) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14106823) * Same problem, it works badly with google recaptcha.

As soon as I activate CF7, the issue arises. To answer your question, the plugins installed on my site are: * Akismet Anti-Spam BackWPup Breadcrumb NavXT Classic Editor Contact Form 7 Elementor Flamingo HTML Editor Syntax Highlighter Jetpack by WordPress.com Master Slider Media Library Assistant Outdated Plugin Notifier SVG Support TablePress Ultimate Post List Widget Options Hummingbird Magic Liquidizer Responsive Table Wordfence Security WP Rollback Yoast Duplicate Post Yoast SEO * Theme is [Spacious](https://wordpress.org/themes/spacious/) (free version).

The issue went away. So I guess my theme is the culprit? If so, what do I do now? Specifically, if I bring this up with theme support, I’m sure you know that they will point to the CF7 plugin and say, “The bug is in that plugin.” If they say that, what would be my best reply? Maybe I don’t mention your plugin just yet, and tell them only, “The issue occurs when I activate your theme.” - This reply was modified 5 years, 2 months ago by [Carl Gross](https://wordpress.org/support/users/carlgross/). * Plugin Author [Takayuki Miyoshi](https://wordpress.org/support/users/takayukister/) * (@takayukister) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14111955) * I’m not sure if the real culprit is the theme. I thought the prime suspect would be Hummingbird because the direct cause of this problem is an invalid insertion of HTML fragment `defer onload='"`, and Hummingbird seems to have a feature to do it. I would advise you to focus on the plugin before reporting to the theme author. * Thread Starter [Carl Gross](https://wordpress.org/support/users/carlgross/) * (@carlgross) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14116200) * >> I would advise you to focus on the plugin before reporting to the theme author. * By ‘plugin’ you mean CF7, correct? * Plugin Author [Takayuki Miyoshi](https://wordpress.org/support/users/takayukister/) * (@takayukister) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14117298) * Hummingbird. * Thread Starter [Carl Gross](https://wordpress.org/support/users/carlgross/) * (@carlgross) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14117404) * Haven’t we already ruled that out as a culprit? * Plugin Author [Takayuki Miyoshi](https://wordpress.org/support/users/takayukister/) * (@takayukister) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14120645) * Have you tested with only Hummingbird deactivated (and clearing cache) and the current theme activated? * Thread Starter [Carl Gross](https://wordpress.org/support/users/carlgross/) * (@carlgross) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14156045) * Sorry for the delay. I just tested the site, with all plugins deactivated, except for Hummingbird. The issue is not present. * I also tested the site in which all plugins were activated, except Hummingbird. The issue is still present. * During the tests, my usual theme (Spacious) was active, and I was sure to carry out hard refreshes. * Thoughts? * Plugin Author [Takayuki Miyoshi](https://wordpress.org/support/users/takayukister/) * (@takayukister) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14158991) * I downloaded the Spacious theme package and searched through the files by “defer”, but found nothing. I don’t think the theme has something to do with this issue. * Thread Starter [Carl Gross](https://wordpress.org/support/users/carlgross/) * (@carlgross) * [5 years, 2 months ago](https://wordpress.org/support/topic/plugin-causing-console-error-syntaxerror-missing-after-argument-list/#post-14162078) * Update: I found the cause of the issue. It was due to custom code that *I* had added in my child theme–code to defer the loading of scripts. Geesh. * So sorry about that–I very much appreciate your time. Let’s consider this resolved.
