Modules page not loading in backoffice

[joergenaj]

I have a 1.6.09 installation, and suddently experienced that Backoffice modules page is stuck. Message is: duplicate content handler is not a valid module name.

 

The strange thing is, I don't have that module folder installed anymore, since it was only working on v 1.5. And searching in the database .sql I find nothing of that module.

 

To try and fix it, I have restored earlier databases and renewed all in modules folder. And the normal things like deleting cache files and Friendly URLs off and on.

No success what so ever. That page is stuck. 

 

I would think it is something in the file system that troubles?

modules may use the db, but they are files in your shop directory.  so restoring db will have little affect.

 

sounds to me you loaded a 3rd party module to handle duplicate content.  does this ring a bell?

 

using ftp, you can open modules folder and look at module names...also if you sort on file time/dates, this gives good view of what may have been changed recently.

Thanks for ideas. And yes, I have installed a clean url handler module. The first was free and it cleaned only categories, next cost a bit, and did only the same. They were third party. And suddently no access to modules.

I have manually moved module by module remote into a tmp folder to see if they were blocking.

No luck...

 

What's in the module folder seem not to matter. Something else is saying stop. Something that remembers the content handler module. But maybe not that module is making the error?

Wow...

 

I fired up Firefox and went to backoffice modules. No problem here.

 

And even with Chrome cache cleaned, still the module error there. Browser specific error???!!

I would find (based on name or time stamp of a particular module folder).  tip: look at the zip file, it will have module folder name.

 

rename the 3rd party module folder by adding _ in front of the name...this will effectively nop the module out of module start up.

 

if that solves loading modules issue, then you can contact the developer, sounds like module is corrupted...

 

I can't help with cross browser question..don't know the module...should be simple....now it just matter of having learnings on how to deal with rouge issue so you can get working again...

[joergenaj]

Thanks again. But also IE can load modules.

I would guess if I rename my Chrome user profile, problem will be forgotten.

 

(I now just have to deal with special characters for our country, that does not display in back office anymore. I use Danish in back office.)

Update...

This is day two. And after login with Chrome, the error is gone. Then one can learn that browsers can be different and a real tricky thing, throwing false scripting errors.

I installed two new commecial modules. Since then I can not load the tab modules.

Well, I checked this with several browsers...

 

I then renamed the two modules by adding _ as prefix, did not help...

I deleted those two modules. Did not help....

 

I can still not call the modules tab

 

PS 1.6.0.9

 

In debug mode I also get error messages but these are related to some thing like this $str = preg_replace('/[^a-zA-Z0-9\s\'\:\/\[\]-\pL]/u', '', $str);

 

I believe this is another bug
