Thank you. That did it.

Disbale CIM

I deleted all of the plug-in files and re-installed version 1.75, but it didn’t help – the plug-in still will not activate. Not sure what could be causing the conflict. I have not installed any other plugins in the past few days.
I see that Google Maps Widget is running a cron event weekly, gmw_cron, but I don’t think that would create a conflict.
Any suggestions?

I tried a couple of them. I did notice that there was a plug-in: WP Ultimate CSV Importer PRO that I got specifically for mass importing products into WPeC and doing some advanced mapping with WP that was running an event every 10 minutes. I disabled it and was able to manually enter my Backup schedules without an issue (one is weekly and one is daily).

I re-activated the plugin and looked at my debug log and everything seems to be scheduled and working as it should. I’ll keep it monitored but it appears the conflict was with WP Ultimate CSV Importer PRO.

BB developers don’t think WPeC would create a conflict. They are doing some more checking.

Here is some more info from my exchange with them:

I doubt WPeC is causing the conflict as well. The curious factor is that I only show 4 programs using the wp_schedule_event() function: WP, WPeC, BackupBuddy, and google-maps-widget (https://github.com/wp-plugins/google-maps-widget/blob/master/gmw-tracking.php).
.
The only plugin(s) that caused suspicion were curation plugins developed by You Brand, but I disabled those.
There is nothing else running that isn’t supported by good developers. If I have to use a plugin for a certain task, I install it, use it, and then disable it, so I’m only running what I need.

Other prominent plugins I run:
Gravity Forms;
All In One SEO;
Analytics for WordPress — by Segment.io (newly installed – fully supported)
Simple Share Buttons Adder by David Neal;
zM Ajax Login & Register by Zane Matthew.

– all other plugins have been disabled and tested one at a time.

You are referring to Brute Force Attacks. It’s common because every spammer, bot, and black-hatted jerk knows that every WP site uses the same registration action (‘wp-login.php?action=register’)…unless… it doesn’t.

Here is a solution that worked great for me. I simply changed that default URL and haven’t had a single spammy request for registration since. (Link to step-by-step solution below).

Also, I used a mod_rewrite to redirect any spammy jerk trying to get in through the wp-login url to a secure page inside my site that you really have to be a human being to navigate through.

This isn’t a WPeC issue, it’s a WP issue that will likely never, every go away on it’s own. Your hosting provider likely has some safeguards to monitor heavy hacking. If they don’t they are just as jerky and the jerks that spam.

<<<SOLVED>>>

In case any of you are interested, it appears to have been a
Wordpress White Screen of Death issue.

Updating to PHP 5.4 solved the issue.

Thanks to the folks at Bluehost for solving it quickly for me.
