15.9. Fixing automatic crawling problems caused by the theme Newspaper 8 (or later)

A lot of customers face this issue. The problem is caused by Newspaper 8 (or later). This is probably fixed in current version of Newspaper theme. If you use Newspaper theme and automatic crawling does not work, you can try the solutions below:

The solution below is suggested by casualbabies.

In the theme’s folder open the file includes/wp_booster/td_cake.php and in about 549th line, replace below line:
```
function _schedule_modify_add_three_days() {
```
to
```
function _schedule_modify_add_three_days($schedules) {
```
Also, you need to do the same replacement in td_js.php file. Thanks creamundo for finding this out as well.

Then, save general settings of the plugin and check Dashboard Page for the next CRON events. If next CRON event times look OK (e.g. x minutes later), then the problem is fixed and the plugin works properly. For more information about how to understand whether there are still CRON problems or not, see Checking if CRON jobs work and fixing CRON problems.
You can try to increase PHP’s memory limit. Then, save general settings of the plugin and check Dashboard Page for the next CRON events. If next CRON event times look OK (e.g. x minutes later), then the problem is fixed and the plugin works properly. If that does not solve it, you can try to increase the memory even more and repeat the process. For more information about how to understand whether there are still CRON problems or not, see Checking if CRON jobs work and fixing CRON problems.
If increasing the memory does not solve the issue, according to a few customers, downgrading your theme to a version below 8 might solve it. First, downgrade your theme. Then, save general settings of the plugin and check Dashboard Page for the next CRON events. If next CRON event times look OK (e.g. x minutes later), then the problem is fixed and the plugin works properly. For more information about how to understand whether there are still CRON problems or not, see Checking if CRON jobs work and fixing CRON problems.
If downgrading your theme version does not solve it either, please temporarily activate one of the official WordPress themes. Then, save general settings of the plugin and check Dashboard Page for the next CRON events. If next CRON event times look OK (e.g. x minutes later), then the problem is fixed and the plugin works properly. The problem was caused by your theme. For more information about how to understand whether there are still CRON problems or not, see Checking if CRON jobs work and fixing CRON problems.
If these did not solve the issue, then the problem was not caused by your theme. Please follow the instructions given in Checking if CRON jobs work and fixing CRON problems.
