Title: "Illegal string offset 'box_blank'" error Last modified: August 21, 2016 --- # "Illegal string offset 'box_blank'" error * [QuickSolutions](https://wordpress.org/support/users/quicksolutions/) * (@quicksolutions) * [12 years ago](https://wordpress.org/support/topic/illegal-string-offset-box_blank-error/) * Was working well, suddenly “Illegal string offset ‘box_blank'” error has occurred across the entire site. Many sites using this plugin have been affected: E.g.: [https://www.google.com/search?q=Warning%3A+Illegal+string+offset+’box_blank’+in+wp-content%2Fplugins%2Fseo-smart-links-business%2Fseo-smart-links-business.php](https://www.google.com/search?q=Warning%3A+Illegal+string+offset+'box_blank'+in+wp-content%2Fplugins%2Fseo-smart-links-business%2Fseo-smart-links-business.php). * I also notice that the home page at [http://www.prelovac.com/products/seo-smart-links/](http://www.prelovac.com/products/seo-smart-links/) is entirely blank…. without any content (probably due to server error?) * Some connection may be between the offset error and the home page being blank? * [https://wordpress.org/plugins/seo-automatic-links/](https://wordpress.org/plugins/seo-automatic-links/) The topic ‘"Illegal string offset 'box_blank'" error’ is closed to new replies. * ![](https://s.w.org/plugins/geopattern-icon/seo-automatic-links.svg) * [SEO Smart Links](https://wordpress.org/plugins/seo-automatic-links/) * [Frequently Asked Questions](https://wordpress.org/plugins/seo-automatic-links/#faq) * [Support Threads](https://wordpress.org/support/plugin/seo-automatic-links/) * [Active Topics](https://wordpress.org/support/plugin/seo-automatic-links/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/seo-automatic-links/unresolved/) * [Reviews](https://wordpress.org/support/plugin/seo-automatic-links/reviews/) * 0 replies * 1 participant * Last reply from: [QuickSolutions](https://wordpress.org/support/users/quicksolutions/) * Last activity: [12 years ago](https://wordpress.org/support/topic/illegal-string-offset-box_blank-error/) * Status: not resolved
