Blank page when clicking "add new" product in back office

[dddanny123]

Hi there,

 

I get a blank page when clicking on "add product". I have turned on the debug mode, and this is the error that I get:

 

Warning: file_put_contents(/var/www/web19/html/presta/config/xml/default_country_modules_list.xml): failed to open stream: Permission denied in /var/www/web19/html/presta/classes/controller/AdminController.php on line 1545 Warning: file_get_contents(/var/www/web19/html/presta/config/xml/default_country_modules_list.xml): failed to open stream: No such file or directory in /var/www/web19/html/presta/classes/controller/AdminController.php on line 1548 Warning: file_put_contents(/var/www/web19/html/presta/config/xml/tab_modules_list.xml): failed to open stream: Permission denied in /var/www/web19/html/presta/classes/controller/AdminController.php on line 2937

 

Every sub-catergory of Catalog (products, categories, monitoring etc) results in the above, or a very similar error.

 

I would be more than grateful if someone could help me with this issue.

 

Thanks!

are you able to change permissions for these files mentioned in error code, for exmple try to grant them 777 chmod.

The above files don't even exist in my xml folder

 

when browsing /config/xml/  the only files I have in this folder are .htaccess and index.php

 

Could these files have been deleted by uninstalling modules? All I have done so far to set up the shop is uninstalling some modules, and deleting all the categories. 

 

Would it make sense to copy these files from the original zip?

co, if it doesnt exist, try to create it and change chmod to 777

[dddanny123]

ok, so I added the following empty xml's to the /config/xml folder:

 

default_country_modules_list.xml

tab_modules_list.xml

 

the debug errors have disappeared, but when creating a new product the page is still completely empty. Anything else I could try?

[vekia]

any additional error appears now? or page is just blank?

[dddanny123]

no, there are no error messages at all now, but the "add product" page is completely empty.
