Use the Accordion plugin of Wordpress. But after changing the name of the site (URL of my site), I have errors including the script add-acc.php.
The error message is:
Notice: unserialize (): Error at offset 0 of 1 bytes.
The line concerned in the file is:
$ accordion_data = unserialize (get_post_meta ($ post-> ID, 'wpsm_accordion_data', true));
I can not solve this problem. As a result, the publications do not appear anymore.
Can someone help me?
thank you in advance
