Did the Court of Appeals err by denying a certificate of appealability when the district court's findings were debatable and multiple constitutional rights were potentially denied?

1. Did the Court of Appeals err by denying a certificate of appealability under 28 U.S.C. 2253 in a case seeking to appeal a district court's order denying habeas corpus relief under 28 U.S.C. 2254 pursuant to a finding of a procedural bar when the correctness of the district court's findings were debatable and the petitioner made a substantial showing of the denial of multiple constitutional rights? 2. Did the District Court err by failing to analyze whether the state rule was adequate as applied to the type of claims in the habeas petition when it denied habeas corpus relief pursuant to 28 U.S.C. 2254 upon finding that such relief was barred because the state courts refused to adjudicate the claims on their merits pursuant to an independent and adequate procedural rule?
