Hey James,
How to find the this <img alt="Cron Job Starts" src="https://www.v2..co.uk/index.php?option=com_payplans&;view=cron&tmpl=component" style="display: none;" />
You can remove this line of code from this PHP file
JoomlaFolder/plugins/system/payplans/payplans.php , you can refer my attached screenshot below.
And this HTML code will not affect any performance issue on your site even it injected on the Payplans pages.
However, we will see if possible to get rid of these code in the future version.
Your manual say CRON server set up - but you didnt say anything is recommend which I can see every 5 mins on screenshot, for server, but when I look at automatic cron, the normal is every 15 mins, which one or is there any recommend value?
You can setup cron job as per your requirement, if you would like to activate automatic cron from backend, this is the following cron internal for this.
Lowest - 1 hour
Low - 30 minutes
Normal - 15 minutes
High - 5 minute
And I noticed our documentation there got some wrong information, we will update this for the cron frequency to 5 minute.
Please correct me if the number is high visitor to the site would that affect CRON, or adjust higher or more lower?
It shouldn't affect anything for the cron job execution.
Or would that is up to hosting provider to adjusting to meet the process?
Regarding this cron interval setting, it's really up to you how long you would like to set for the cron interval, but I would recommend you that set the cron interval to 5 minute.
I understand the CRON setting on Payplans 3.5 was easier.
Actually Payplans 3 Cron setting is the same in Payplans 4.
And the older version of PayPlans 3.x also will inject this cronjob HTML on the pages, but it's strange why it's only happen on Payplans 4 which inject this HTML code into your RS Form Pro! DJ Classifieds email template, is it possible for you to setup one of your development site and provide us with your site backend, FTP and guide us how to replicate this so we can able to check this on your development site?
Thank you for understanding
