Title: SEO data optimization 403 Last modified: May 26, 2021 --- # SEO data optimization 403 * Resolved [hesselwellema](https://wordpress.org/support/users/hesselwellema/) * (@hesselwellema) * [5 years ago](https://wordpress.org/support/topic/seo-data-optimization-403/) * Hi, * Pressing the button SEO data optimization results in a message: * `Oops, something has gone wrong and we couldn't complete the optimization of your SEO data. Please click the button again to re-start the process.` * The console states: * `Failed to load resource: the server responded with a status of 403 () /wp-json/ yoast/v1/prominent_words/save:1` * – WordPress and all pluginns are up to date – It is a small website – Your supportdepartment already had me do stuff with the Yoast Test Helper plugin * The problem persists * Checked with the HSP that hosts my website and according to them comodo WAF thinks the call is a Blind SQL Injection Attack. * `object_id found within ARGS_NAMES:data[0][object_id]: data[0][object_id]\"] [ severity \"CRITICAL\"] [tag \"CWAF\"] [tag \"SQLi\"]"` * The HSP and Comodo are unwilling to help me. The first because they find it not to be part of their responsibilities. The latter because I am not their customer. * Currently I am not able to use some features of the premium version of your plug- in and I can’t do anything about it. * My question: When will you solve this. - This topic was modified 5 years ago by [hesselwellema](https://wordpress.org/support/users/hesselwellema/). - This topic was modified 5 years ago by [hesselwellema](https://wordpress.org/support/users/hesselwellema/). - This topic was modified 5 years ago by [hesselwellema](https://wordpress.org/support/users/hesselwellema/).

It could be a security plugin that might be causing this. We have received similar reports from other users where the issue was caused by their web host’s security measures. Please contact your web host to check the mod_security settings that prevent our plugin from accessing the REST API request: /wp-json/yoast/v1/prominent_words/save * If there are no mod_security settings preventing access at the server, you may have a custom .htaccess rule that limits access to the WordPress REST API. Please review any security restrictions and whitelist the Yoast plugin for accessing the feature. * Lastly, if you are using caching on your site, you may need to adjust cache settings to remove /wp-json/yoast from the caching. If you are not sure how to do that please contact your host provider and/or caching plugin authors. * Once that has been resolved, you should be able to re-run the SEO data optimization process and it should complete without any more errors. * Furthermore, per the [forum guidelines](https://wordpress.org/support/guidelines/), we cannot answer questions about our premium products. If you have a Yoast SEO Premium subscription, please [contact our support team](https://yoa.st/support) directly. * Thread Starter [hesselwellema](https://wordpress.org/support/users/hesselwellema/) * (@hesselwellema) * [5 years ago](https://wordpress.org/support/topic/seo-data-optimization-403/#post-14485113) * Hi [@maybellyne](https://wordpress.org/support/users/maybellyne/) * I tried to explain that the problem is caused by a rule in Comodo WAF. My problem is that they (Comodo and my HSP) are not willing to do anything about it becayse they think your implementation is wrong, * Hence my question: when will this be solved? * [Md Mazedul Islam Khan](https://wordpress.org/support/users/mazedulislamkhan/) * (@mazedulislamkhan) * [5 years ago](https://wordpress.org/support/topic/seo-data-optimization-403/#post-14488415) * Thanks for your clarification. First thing first, are you currently running Yoast SEO Premium? If yes, please send us your query over at the [support@yoast.com](https://wordpress.org/support/topic/seo-data-optimization-403/support@yoast.com?output_format=md) email address so that we can address the query better since you have a premium subscription. The forum here is only specific to Yoast SEO-free users. * On the other hand, we understand that you are unable to run the SEO data optimization due to the Comodo WAFs security rules and Comodo+HSP is unwilling to help you. Let’s see what’s going on here. * Yoast SEO runs concurrent HTTP requests when running the SEO data optimization. However, some web hosting provider and security firewall like WAFs by Comodo blocks the relevant requests and as such, Yoast SEO can’t perform the SEO data optimization. If Comodo and HSP are unwilling to help by clearing the relevant WAFs rules on your website, we are afraid to say that we can’t help as this is out of our control. Only they (Comodo and HSP) have access to the relevant control panel to make that happen. * We hope that clarifies your query! If you need more information or assistance, please send us an email at our support inbox as mentioned initially. * Thread Starter [hesselwellema](https://wordpress.org/support/users/hesselwellema/) * (@hesselwellema) * [5 years ago](https://wordpress.org/support/topic/seo-data-optimization-403/#post-14488626) * Tnx. I spent literally hours already discussing this with all relevant parties whom are all pointing to each other. I will rephrase and hopefully you can help me with some information. * Comodo blocks the Yoast http requests because they resemble a “Blind SQL Injection Attack” We are (like most starting businesses) relying on a shared hosting environment for our wordpress site. THe HSP or Comodo can’t just loosten their rules just for a single plug-in for one customer. This would be risky (WordPress is vulnerable to SQL injection attacks) for other customers but would also conflict with their businessmodel. * Your colleagues are aware of this ([https://github.com/Yoast/wordpress-seo/issues/16018](https://github.com/Yoast/wordpress-seo/issues/16018)) and my only question was: when will this be solved? * Plugin Support [Maybellyne](https://wordpress.org/support/users/maybellyne/) * (@maybellyne) * [5 years ago](https://wordpress.org/support/topic/seo-data-optimization-403/#post-14490843) * Hello, * We see that you have also reached out via email. We will go ahead to mark this thread as resolved to keep the forum tidy. * Your email will be responded to by the technical support team. * Thanks. * Thread Starter [hesselwellema](https://wordpress.org/support/users/hesselwellema/) * (@hesselwellema) * [5 years ago](https://wordpress.org/support/topic/seo-data-optimization-403/#post-14493934) * Tnx. I got this reply from your colleague. I think it is good to share this so people can test this before the final decision to purchase a premium version of your plugin (which I do really like but cannot use to its full extend): * > `Thanks for getting back to us.
