Can't delete TV

sottwell — Feb 18, 2013, 02:30 PM

Ever since the amsterdam server went down the other day, I'm not able to delete or remove a specific TV from a template without causing creating or editing resources to crash with a white screen or a "bad gateway" error. The TV isn't being used anywhere. Other dev installation on the same server don't have the problem, nor do any of my other MODx installations on other servers. I've checked the database, and the tables are all OK. This has taken me two days to pin down exactly what is causing the error, after losing several hours of work since the only resolution after deleting the TV was to restore the site from backup. Does anybody have any idea what's going on here?

Ok, I solved the problem. I created new templates, with the same template content as the originals, and used Batcher to change all the resources to use the new templates. Then I deleted the old templates (changing my default template to be one of the new ones) and deleted the errent TV. Apparently it was something to do with the templates rather than the TV itself. Who knows? All is well now, so who cares?

I can change the name, the default content, and input option values. I can't change anything else about it, and it must be available to any resource that I want to edit or create (default template). This is on the Cloud, so it's not a problem with mod_security. The MODx team is looking into it, since it started happening immediately after the paas2.ams server crash, and I'm pretty sure that deleting that TV was the last thing I did in the previous work session, so I can't say if it caused the problem before the crash. Maybe that's what caused the server crash .

It doesn't seem likely that a date/timezone mismatch would affect just one TV. mod_security? Does the TV have a suspicious name?

No. I even disabled all plugins. The TV had not been used anywhere for some time; it had no values anywhere. A search through the file system didn't find any reference to it, nor did a search through the database. I couldn't find any difference between this TV and any other TV in the database. I do question the timestamp on the error log Jason reported via email (I got the same errors in my MAMP installation only with a more relevant timestamp) - what does America/Chicago have to do with a server in Amsterdam?

Quite the mystery. Is that TV referenced in plugin code anywhere?

I'd better not; the client wouldn't be real happy about that. I've finally gotten my email address straightened out with the MODx tech people, so it'll get sorted out.

@sottwell - you could send me the cloud if you like, and I could see if I can replicate the problem?

I copied the site to localhost, and spent hours and couldn't get it to work. I replaced all core and manager files and folders. I removed all packages. I deleted everything except that TV. As long as the TV exists, is not in a category, and has access to the templates a resource is using, editing/creating resources works. Change any of those things, or changing its input type, and it either white-screens or gives a bad gateway error.

@sottwell - Hope you get to the bottom of the problem. Only thing i've noticed since the downtime are a few NGINX gateway error messages when logging in to the manager.
