Hi there,
For those who upgrade Dolphin from a while, there is a problem in the Page Builder. When you click on "Reset Page", instead of the "factory state" you have... nothing! no more blocks...
To fix that, go into the folder ./admin/default_builders/ and open all .sql files (or just the one you need).
Then replace all the IDs by '' (two apostrophes).
The ID is the numer just after VALUES.
For example :
INSERT INTO `PageCompose` VALUES(31, 'video', '960px', '', '_Video', 1, 0, 'ViewFile', '', 1, 50, 'non,memb', 380);
becomes
INSERT INTO `PageCompose` VALUES('', 'video', '960px', '', '_Video', 1, 0, 'ViewFile', '', 1, 50, 'non,memb', 380);
Hope that helps!
