Order totals modules not appearing in admin

No, there is the same list of file names in that directory.

Well, um, I'm trying to sort out a problem with the Edit Orders plugin. A long story, but in the context of working through that, ie., to get back to a base install with no trace of files from that plugin, I noticed the anomaly with the order total modules. I thought I needed to deal with that first, before trying to sort out the Edit Orders mess. I should say that the mess is not down to the plugin.

I am assuming that if I get back to the original install state vis. all that kind of stuff, I can clear that up. The essence of that problem though, is that order totals aren't displayed. Hence, my newfound interest in the order totals modules!

On the PDO_SQLITE.so error, my server people said I should talk to [zencart]. Not looking to criticise anyone, but what is the essence of this error? What steps need to be taken to overcome this?

Are you using a custom php.ini file?
When my host upgraded from php 5.2 to 5.3 It gave me similar errors as I was still using the php.ini file from php 5.2
When I replaced it with the 5.3 php.ini file this error went away.
Again this is something your host should help with.

The PDO_SQLITE.so file was referenced in the earlier php.ini file
I believe it was commented out in the current version

Interesting. No custom ini file. But I get the idea that it has something to do with a php upgrade. My server people are really good. But the response from a 'first level' support person was that I should talk to [me]. I recall a similar thing some time ago - may not have been with zencart - and a higher level support person said something about PHP versions. But nothing specific. (server people good? Generally, yes, very good. There must be a too-hard basket nearby.)

I also get this error constantly, which I am told is to do with PHP:

[07-Mar-2014 03:47:05 UTC] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20090626/PDO_SQLITE.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20090626/PDO_SQLITE.so: undefined symbol: php_pdo_register_driver in Unknown on line 0.

PHP triggers that error every time it starts (which on some server configurations could actually be on every page visit) when the PHP configuration on the server is set to specifically load support for that driver but the driver can't be located. In this case it's for the PDO driver for the sqlite engine.
A competent server tech support person would know this.

Zen Cart doesn't use SQLITE, nor does it use PDO. Thus why Ajeh advised you that the problem must be fixed by the server administrator.

[godt]

Thank you for that explanation Dr Byte. I will put that to my people in precisely that way. Much appreciated.

On the other matter, any thoughts on how to get order_total modules appearing? It doesn't seem likely that edit_orders files would cause that.

[Ajeh]

Could you check the files in:
/includes/modules/order_total

and make sure that those files are the Code files and not somehow the language files?

Could you compare the file, on the server, for:
/your_secret_admin/modules.php

to a clean Zen Cart v1.5.1 copy of that file?

A good compare tool is Beyond Compare from scootersoftware.com ...

[godt]

Thanks. I'll do that.

I compared the admin/modules.php file on the server to a clean ZC copy, and Winmerge showed no difference. And then copied new versions of /includes/languages/english/modules/order_totals files to the server, as well new copies of /includes/english/modules/order_totals. Then replaced all files that the 'Edit Orders' module had added or changed.

I still have no totals showing, and no order_total modules displayed.

I also logged in through a second admin directory that I had installed some time ago for another purpose, and I get the same absences there. Which would seem to suggest a corrupted file outside of /admin, or a database issue.
