PKP Index Problem about adding new journal

I can not add my journal to PKP Index.
After Registering, I try to fetch the journal OAI link it persistently gives the same message:

Errors occurred processing this form:
EntityRef: expecting ‘;’

Could you help me to fix the error please?
Thank you in advance

Hi @euser,

Is your website public? If so, could you post or PM me the URL to it?

It was related to the algorithm of the web address regarding the nginx server as OJS was designed for Apache servers. Now it is fixed.
Thank you for your concern
