Admin Panel and Shop Frontend Giving localhost 500 error

[Mohsin_Javaid]

I am trying to migrate from oxid version 4 to oxid version 6

I am using this guide here: https://docs.oxid-esales.com/developer/en/6.0/update/eshop_from_53_to_6/index.html

Problem is in database migration. I installed oxide version 6.0 from composer and after installation i completely emptied its database. Imported my oxid 4 database and ran the two scripts:

migrate_pe_5_3_to_6_0.sql
migrate_pe_5_3_to_6_0_cleanup.sql

After that i ran the given the commands:

vendor/bin/oe-eshop-db_migrate migrations:migrate
vendor/bin/oe-eshop-db_views_generate

Now when i go to localhost and try to access my shop or its admin panel. The only thing i get is

localhost is currently unable to handle this request.
HTTP ERROR 500

and there are no error logs in EXCEPTION_LOG.txt

What should i do? What am i doing wrong here?

You can set $this->iDebug = 1; in config.inc.php (enable write access first) and see if an error is displayed, otherwise you have to get access to the apache webserver error logs.

@leofonic I set $this->iDebug = 0 to $this->iDebug = 1 and also check apache error logs.
The first error i get is this:

Fatal error: Maximum function nesting level of ‘256’ reached, aborting! in D:\UwAmp\www\oxid_pe_6_one\vendor\oxid-esales\oxideshop-ce\source\Core\NamespaceInformationProvider.php on line 76

This is a core file, i dont think i should be making changes in that. What could be wrong in that can you please guide ?

[leofonic]

There might be an error with module configuration, you can reset module info with this SQL:

delete from oxconfig where oxvarname in ('aModulesHistory','aModuleVersions','sUtilModule','aDisabledModules','aLegacyModules','aModuleFiles','aModulePaths','aModules','aModuleTemplates');

and clear /tmp right after this sql.

@leofonic That worked like a charm! i am now logged in to admin panel, but however i still can’t access the shop frontend. I get this error:

Warning: Smarty error: unable to read resource: "message/exception.tpl" in D:\UwAmp\www\oxid_pe_6_one\vendor\smarty\smarty\libs\Smarty.class.php on line 1100

Please know that, i am migrating from so i guess theme files maybe missing, so while i am porting theme files to oxid version 6, Let me know if its the theme files issue or something else by looking at the error mentioned.

Please bare with me as i am totally new to this oxid shop, and don’t know how to debug. Thankyou!

[leofonic]

If you have admin access you can set the theme to “flow” in extensions, this should fix the error.

@leofonic i ported the theme files , and i got this error:

OxidEsales\EshopCommunity\Core\Exception\SystemComponentException-OxidEsales\EshopCommunity\Core\Exception\StandardException (time: 2019-07-15 15:11:17): [0]: Function ‘getFbAppId’ does not exist or is not accessible! (OxidEsales\Eshop\Core\ViewConfig)

it maybe because facebook got removed from oxid v6, should i install it via composer ? as mentioned in the documentation ?

[leofonic]

Yes facebook was removed, i think it’s available as an extension. There might be some other errors in theme, you can check whether it’s theme-related by switching to flow theme and see if the error disappears.

[Mohsin_Javaid]

I switched to default theme which is ‘flow’ and it removed error. But however i am always redirecting back to this url:

http://localhost/oxid_pe_6_one/source/mein-konto/

Also i am getting these things below the page:

[leofonic]

The things below the page is the debug info, to switch off set iDebug to 0 again. Redirection to mein-konto: you might have private sales activated in master settings, core settings, settings, private sales.

[Mohsin_Javaid]

Yes, private sales was enabled, i disabled that and now i am on shop homepage and i am seeing some products. And okay i’ll turn that iDebug off again that would be great. So is my database migration completed i guess?

[leofonic]

Yes all fine!

Thankyou for all the help
