Hi,
yes with default wordpress theme, still I get the same error. Where is the issue from?
Can you please check and at least tell me what is the problem . because it happens since I installed the Woodmart basic demo import.

1- I know it doesnt require any size of images. I asked your opinion and recommendation to look better and faster. what is the sizes of demo content images and what format should i save to get the best results?

2- I know how to to customize the menus and where. my problem is when i delete some of the demo pages the menu goes weird.

3- Thanks for No. 3

4- Thanks for No. 4 I think I find it

But please find me a solution for the HTTP Error I need to deliver the job to my client ASAP.

Regards,
