A couple of message replies with more information from me and they offered what I posted. * I’m sure a working solution will be in the next release. * My understanding of support here is that it’s done on best effort basis, and dependant in the developers availability. Especially for a plug-in that has no cost involved. I’ll always take a pro option for any plug-in that I’m using to support the developer. * This particular plug-in fit the requirements for me perfectly. * [Saúl Ramírez](https://wordpress.org/support/users/blusnirvana/) * (@blusnirvana) * [4 years, 7 months ago](https://wordpress.org/support/topic/error-technical-issue-affecting-site/#post-14965544) * Hello [@ausdamo](https://wordpress.org/support/users/ausdamo/) excuse me could you tell me where I find that line of code that you mention to solve the error. * [ausdamo](https://wordpress.org/support/users/ausdamo/) * (@ausdamo) * [4 years, 7 months ago](https://wordpress.org/support/topic/error-technical-issue-affecting-site/#post-14965599) * Oh no! * I’ve made a complete mistake, sorry to you both. * There are two plugins I’m troubleshooting and this is the other one. I have confused myself and posted to the wrong thread. * [Saúl Ramírez](https://wordpress.org/support/users/blusnirvana/) * (@blusnirvana) * [4 years, 7 months ago](https://wordpress.org/support/topic/error-technical-issue-affecting-site/#post-14965606) * hehe I understand, Schema support is still not responding. I have sent several messages and without success. * [ausdamo](https://wordpress.org/support/users/ausdamo/) * (@ausdamo) * [4 years, 7 months ago](https://wordpress.org/support/topic/error-technical-issue-affecting-site/#post-14965624) * I am so sorry! * For this one I’ve set a Cron the delete the log so it doesn’t grow too large. Not ideal but a stop-gap measure. * [Saúl Ramírez](https://wordpress.org/support/users/blusnirvana/) * (@blusnirvana) * [4 years, 7 months ago](https://wordpress.org/support/topic/error-technical-issue-affecting-site/#post-14965647) * I disabled the Wp Cron, because the process was running in 1 – 3 minute intervals, it was filling my error log. * Plugin Author [Hesham Zebida](https://wordpress.org/support/users/hishaman/) * (@hishaman) * [4 years, 7 months ago](https://wordpress.org/support/topic/error-technical-issue-affecting-site/#post-14966863) * I’ve added a check before calling the class, which should solve the error. * Just pushed an update including the fix, please update to version 1.7.9.3 * Let me know how it goes. * [Saúl Ramírez](https://wordpress.org/support/users/blusnirvana/) * (@blusnirvana) * [4 years, 7 months ago](https://wordpress.org/support/topic/error-technical-issue-affecting-site/#post-14967055) * Thank you very much, [@hishaman](https://wordpress.org/support/users/hishaman/) I will update the plugin and follow up on the error.
