error: cannot redeclare zen_parse_url()

[delia]

I was working on fixing a file in admin when all of a sudden I started getting this error message when trying to access orders:

[21-Mar-2015 11:34:05 America/Los_Angeles] PHP Fatal error: Cannot redeclare zen_parse_url() (previously declared in /home/user/public_html/admin/includes/application_top.php:160) in /home/user/public_html/admin/includes/application_top.php on line 186

Yes, it was orders I was editing but I uploaded a clean copy of the 1.5.4 orders file and it's still happening. I changed nothing else on the site immediately prior this error.

Since the only place I know of zen_parse_url is in the configuration file, this makes no sense whatsoever.

So seeing as the error appeared when accessing orders, what has changed since the last time orders were accessed (not just immediately before)? What other plugins are installed? Is this prohibiting use of or access to the admin page now? If not, may want to see where/how else zen_parse_url or the file that contains that function is called... It may be that a store side file was uploaded to an admin side location for example...

Were trying to resolve a different admin issue, so what was that issue and what was done to attempt to resolve it?

I had overwritten the orders file that had the edit orders mod in it - very little code changes. So after getting that code back up, then found the edit_order.php was throwing an unexpected error. So I was just checking everything all over again when this error started happening with the orders.php. I'm quite sure I made no changes when this started. What I did do was upload the default orders.php file for 1.5.4 but the error is still happening no matter which orders.php I use. I have found no other pages in admin with any errors. Haven't checked everything but spot checked.

There are various mods but none that require edited core files in the admin beyond the edit orders and all are standard mods - but as I said I had not uploaded any new or changed files beyond the orders.php file. I have looked at dates and times on the admin files. I'm quite this was not in a reaction to something I did.

Which means what? I don't know.

After a break and cup of tea, I'd double check the file "/admin/includes/application_top.php". I would "guess" it differs from a stock Zen Cart 1.5.4 copy or the upload may be corrupted.

Out of curiousity, what is the version of PHP? Does your host have APC, Xcache, OPcache, or another PHP optimizer / accelerator enabled? Any sort of load balancer, proxy, or cache at the hosting provider?

[delia]

nope, that was one of the files upgraded.

Remember this did no start happening until 2 days after the upgrade.

PHP is 5.4.3 with nothing that looks odd to me. More stuff than some hosts but nothing like what you are referring to.

Next "guess" would be "/admin/orders.php" (or the admin page in question) may be calling "/admin/includes/application_top.php" twice.

[delia]

It happens even with the default orders file.

Sounds like it's time for a complete compare of all files against originals: http://www.zen-cart.com/wiki/index.p...Obscure_Issues
(And checking for "extra" unexpected files, such as backups you made but kept the .php on the end mistakenly)

Was thinking I might just go upload all the 1.5.4 files again in admin. Definitely got to do something major! Thanks.

Well, I guess this one shall remain a mystery. I took his original admin files and upgraded again, adding in the one extra mod and all is okay there. I hate it when I can't figure out what went wrong.

Thanks everyone!
