Fatal error after updating to 3.6

(Sorry for the delay; I never got notification.)

This is not multisite. This is plain vanilla WP 3.9.1.

I’ve now deactivated, deleted, reinstalled, re-[tried] to activate it, about 20 times now. I always do it through the Add New function, not via manual FTP. (But I do have FTP access if you want me to try that.)

I’ve also used WP-Optimize to clean my tables.

I’m totally stumped. Any further suggestions? (You mention a log but I’m not sure what log you would want or how to get it.)

Did you mean 3.6.1 or 3.6.2? As of today, the latest appears to be 3.6.1.

I did try updating to 3.6.1 and am getting the same results. If 3.6.2 is about to be released momentarily, I will try it as soon as it’s public.

I can’t be sure that this is the cause, but on my main site and also on my clone, I’ve now discovered that there might be a conflict with a sub-plugin of Easy Digital Downloads (EDD) called “Easy Digital Downloads – CSV Manager.” (I’ll call it EDD-CSV)

(Yes — I need that plug-in — Ultimate CSV Importer doesn’t do that type of CSV import as far as I can tell.)

Easy Digital Downloads itself seems to be fine. I’ve succeeded in activating Easy Digital Downloads and Ultimate CSV Importer and now they are both happy.

However, if I have those two activated, and try to activate EDD-CSV, I get errors or a white screen. If I have EDD and EDD-CSV activated, and try to activate Ultimate CSV Importer, I get a fatal error.

Basically, no combination of EDD-CSV and Ultimate CSV Importer works properly.

But this used to work fine, a few weeks ago. Any chance you could look into whether there’s a conflict there or whether there is something unique to my site/database?

(Both EDD and EDD-CSV are free plug-ins.)

Going through it step-by-step now in my sandbox site:

1. To start, EDD is deactivated, EDD-CSV is activated, and Ultimate CSV is activated.

2. I activate EDD. I get a white screen. I reset this by going into the FTP and renaming the EDD plug-in folder temporarily. Then I reload my admin area, it works, and the Plug-ins page tells me EDD has been deactivated due to an error (file doesn’t exist). This makes sense.

NEXT ATTEMPT:

1. EDD is newly deactivated. I also deactivate EDD-CSV. Ultimate CSV is activated.

2. I activate EDD. It activates normally.

3. I now activate EDD-CSV. I get the white screen, which, again, I resolve by renaming plug-ins by FTP.

THIRD ATTEMPT:

1. I make sure all three plug-ins are deactivated.

2. I activate EDD then EDD-CSV. Both activate normally.

3. I then activate Ultimate CSV. It gives me this error: “Plugin could not be activated because it triggered a fatal error.” (There is no further text to explain.)

I’m using the latest versions of everything.

I had the trio working fine up until a few weeks ago. Actually what triggered it was: I was in the WP back-end doing a routine update to Ultimate CSV, and while it was updating, it hung. After half an hour, I eventually had to close the browser window. I knew this update may or may not be complete, but from that point on, the above problems started, and I couldn’t get Ultimate CSV activated any more. (Hence the top of this thread.) Only today did I connect the dots that it might be somehow linked to EDD-CSV.

I’m working in a sandbox site and would be happy to grant access to any developer who wants to see it for themselves. (Or I can do a screen cap video.)

Thanks everyone!

Thank you Smackcoders! Just sent you an e-mail via that form.
