[Solved] 500 Internal Server Error FileApiHandler double slash

Dear all,

We got the error below after moving to a new server, Ojs 3.1.1.4

[12-Oct-2019 04:43:13 UTC] FileApiHandler: File home/u7141910/public_html/files/journals/13//articles/926/submission/proof/926-145-2257-1-10-20191003.pdf does not exist or is not readable!
[12-Oct-2019 04:43:13 UTC] ojs2: 500 Internal Server Error

There is a double slash at home/u7141910/public_html/files/journals/13**//**articles
I have no idea to solve it

Thanks

@Vitaliy
