#4326 – Database entrys with blank newurl field

Hi

This denotes a 404. You should not delete from the database, but instead the toolbar tools. For instance you can purge all 404 URLs (as you seem to be willing to do) by using the corresponding button on the 404 URLs manager.

In any case, you should never delete or modify anything in the database if you have the "URL disk cache" feature enabled. This will cause you a lot of trouble, although not immediately. Please avoid touching the db as much as possible.

Hi

1 -

First, I'm not sure where to do that

It's all in the configuration, under the "By component" tab

2 -

Second, what does that mean as far as friendly urls?

There might be some changes in URLs, but that's entirely up to the JCEvents component, and the way its router.php file is built.

3 -

Also, in the database there are many entries with no date added. Is that normal?

Yes, a normal URL does not have a date added column

4 -

Finally is there a way to safely delete entries from JC Events through your interface? And not 25 at a time, but in bulk?

Not if you have have millions of them to delete, that will have to be done in the DB

5 -

And finally, what do you mean I will see problems in the future? What kind of problems? I've already deleted many calander

Same, it's in the configuration, under the Advanced tab

And finally, what do you mean I will see problems in the future?

If the cache is enabled, then URLs are stored in DB and some of them are also stored in a disk file, for speedier access under certain conditions . This feature is now disabled by default, as it does not have the benefits it once had.
If it is enabled, and you delete some URLs from the DB directly, then there is now a discrepancy between the disk cache and the db content. The cache is loaded first so for instance, if you delete some JCEvents URL in the DB, and it's in the cache, sh404SEF will keep using the old version, because it finds it in the cache. This leads to incomprehension, and issues with people changing settings furiously, and not seeing the expected results.

The disk cache should be disabled on most sites. Absolutely disable it before you do any dabases manipulation.
