Drupal 6.x

Hi

I tried to migrate the site from dev to production and I am getting below errors:

warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'ctools_access_menu' not found or invalid function name

I have checked it google community and tried to fix u no luck yet, I have tried to clearing cache, disabling modules etc, but no luck, please help me in this regard.

Steps which I performed

I can't get past Drupal's 'Supply your info' page. Ftp credentials fail. Web host claims they're valid. Any ideas?

I own an e-commerce website built on Drupal 6. It is a membership site and has been in operation since July, 2011. The e-commerce process operates with MoneyScripts and PayPal. The site uses CloudFlare, Sucuri and Symantec/VeriSign EV SSL. Since developing the site, the web design company has been performing on-going maintenance, i.e. performing updates, as needed and special projects as they arrive. Recently my web design company informed me that they were closing their business on 01 August, 2015. Other than the very occasional hiccup, the site is largely trouble-free.

i am having a problem getting it to work. i understand this issue could
be with drupal, sox, my os, or my apache server. i manage a vps.

track'n stack allows for collaborative music creation. pretty cool and unique to my knowledge.

when i upload a file, the prompt says "processing mixdown" and stays that way.
since there is only one file there, i don't understand why it says this.
if i upload a second file after checking out the first file, the same thing happens.

Hi,

I have created a custom content type and added a field_attachment field. I create new content using the New content type and add some files. When I browse the page / node, the files are listed together with very large icons in the top.
I am unable to find out how to override these default settings.

I think I need to create an override file, but how ?

Please help

Hello - total Drupal novice here. I have recently successfully migrated two Drupal instances from one host to another.
