please help !!

Answer 1

Please check

• theme

• core_config_data table for theme entry

• eav_attribute

• catalog_product_entity_varchar

• catalog_category_entity_varchar

• cms_page

• design_change

for assign theme to products,categories,cms pages, custom design.

Answer 2

Maybe in core_config_data contain wrong active theme.

Try to find

select * from core_config_data where path like '%theme%';

and check that theme exist into theme table if not then try to change theme id and check it
