We are setting up a quite ambitious multilingual Drupal site (check out at http://www2.bridge-initiative.org), and are about to finish, but encountered a problem in managing additional blocks. We have created still another multilingual block, which will have 5 language versions. I have succeeded in creating the first of those 5 blocks, but Drupal now doesn't accept anymore. Any other simple block I create replaces my previous block (takes its name, and place in the multilingual block setting).
I suspect this may be due to Drupal limits on blocks. We already have 27 active blocks, many of them being multilingual. Each multilingual block has 3 to 5 simple blocks. So that's probably over 100 blocks, not counting 5 multilingual blocks we would want to delete. But nothing is apparent on how to delete multilingual blocks, from the administration panel. Which leads me to my second question.
In summary:
1 Does Drupal have a limit on the number of simple and multilingual blocks you can manage in a site?
2 How do you delete inactive multilingual blocks, without fiddling in the tables?
If answer to question 1 is "no", could someone give me a hint as to where the problem comes from?
