There are some problems with your database. Normally it is safe to try to fix these problems automatically however if your community is large, you may want to run the necessary queries manually. If so, the queries to run are:
ALTER TABLE `ipb_core_clubs` DROP INDEX `location_lat`, ADD KEY `location_lat` (`location_lat`,`location_long`), ADD KEY `type` (`type`), ADD KEY `name` (`name`(191)), ADD KEY `content` (`content`), ADD KEY `last_activity` (`last_activity`);
CREATE TABLE `ipb_forums_forums_new` LIKE `ipb_forums_forums`;
ALTER TABLE `ipb_forums_forums_new` ADD COLUMN `id` SMALLINT NOT NULL AUTO_INCREMENT , ADD COLUMN `topics` INT UNSIGNED NOT NULL DEFAULT 0 , ADD COLUMN `password` VARCHAR (32) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL , ADD COLUMN `password_override` VARCHAR (255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL , ADD COLUMN `last_title` VARCHAR (255) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL , ADD COLUMN `qa_rate_questions` TEXT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NULL , ADD COLUMN `solved_stats_from_cutoff` INT NOT NULL DEFAULT 0 , ADD PRIMARY KEY (`id`), ADD KEY `forum_password` (`password`), DROP INDEX `widget_performance`, ADD KEY `widget_performance` (`min_posts_view`,`password`(20),`password_override`(160),`can_view_others`);
INSERT IGNORE INTO `ipb_forums_forums_new` SELECT * FROM `ipb_forums_forums`;
DROP TABLE `ipb_forums_forums`;
RENAME TABLE `ipb_forums_forums_new` TO `ipb_forums_forums`;
ALTER TABLE `ipb_gallery_images` ADD KEY `image_file_size` (`image_file_size`), ADD KEY `image_views` (`image_views`);
ALTER TABLE `ipb_cms_databases` ADD COLUMN `database_comments_perpage` TINYINT NOT NULL DEFAULT 0 ;
