No response from journal editors
Over a month seems normal to me. The editor will need time to consolidate the reviewers' comments and decide on whether to accept, reject, or return the paper to you for revision. It might take longer if the recommendations from the reviewers are conflicting. Bear in mind that the editor has other responsibilities and might handle a number of papers at the same time.

Usually in the online submission system there will be an option to send a message to the editor handling the paper. You can try it if there is one. I would not suggest contacting other editors in the editorial board as they may not be involved with the review of your paper.
