We are using JA Megafilter to search for Joomla articles with search instances based on Joomla fields. We have 2737 items in the data base. A year ago, indexation started not to work anymore, resulting in a page missing error. Using the Cron task link to run indexation enabled us to proceed to indexation. SInce recently, the Cron task solution does not work anymore : it performs ("Cron done" displays) but without indexing the recent items. Curiously enough, on a local version of the website indexation works fine. We have increased all php parameters (max_execution_time = 300, max_input_time=600, max_input_vars= 10000, memory_limit=2G, etc) of the Apache server of the production site but with no success. Would you have any comments to advise us?
